Description

Technical area

The The invention relates to a device for documenting a by change of location characterisable physical exercise a person with a mobile receiving unit for signals to the geographical Location determination that generates location data, a sensor unit for detection at least one person-specific vital parameter for generation vital signs, a data recording and storage unit, as well as a data processing unit for processing the location and vital data. Further, a method for documenting and verifying a locomotive characterizable physical training explained to a person.

State of the art

Recording devices for purposes the documentation of physical upgrading work, especially in the form of sports activities, are dependent on the respective sports or movement in a variety of forms known. For example, heart rate monitors with memory function, used by endurance athletes, for example, joggers or long-distance runners be on the one hand a current pulse information during the Sport exercising on the other hand by means of subsequent evaluation during the Duration of exercise recorded Pulse information therapeutic and / or training-optimizing Gain knowledge. Such pulse watches have a directly on the body to be attached pulse sensor, usually wireless sensor signals for recording and storage purposes and transmitted to a wristwatch for visual display.

Further are more sophisticated systems for capturing, recording and Storage of a variety of different measurement parameters well-known, so for example in the field of cycling usable minicomputer, the preferably mounted on the bicycle handlebar and in the way of a multi-channel recording to record various sensor signals in the form of separate time functions and over a display unit the respective athletes visually for presentation to be able to bring. In addition to those described with heart rate monitors Have sensors for pulse detection Such minicomputer systems via a Variety of other sensor units, such as. Sensors for detection the bicycle pedaling frequency, the rotational speed of a wheel, the current air pressure, etc.

Furthermore are systems for recording the current geographical position known the reception and evaluation of satellite-based navigation signals good, that of global navigation satellite systems, hereafter GNSS called to be sent to Earth, such as the American Navstar Global Positioning System, GPS for short, the Russian Glonass and the planned European Galileo system.

meanwhile are among the variety of commercially available satellite signal receiving devices for location and navigation devices too available, the next to the ability a highly accurate geographical location via vital signs recording channels feature For example, for detecting and recording the pulse or heart rate of a respective user. For example, be in this context equipment the company Garmin, the device series Edge (registered Brand).

all previously on the market devices for recording and ultimately The disadvantage is the documentation of sports activities of persons that is an afterthought Manipulation of the recorded data can not be excluded can. So it is possible to read the respective data record and subsequently to a computer with to manipulate appropriate software in a manner so that the manipulation is not or only with great effort is recognizable. For example. could The measured and recorded time for the completion of a training session be reduced, which ultimately improves performance of the respective athlete in deceptive Ways can be improved.

to Encounter of manipulations on vergelichbaren records, the through software Post processing in an abusive way carried out can be are GNSS receivers known for recording so-called tracklogs - this is one within each of a recording period traveled as temporal Sequence of coordinate points with respect to the geographic length, the latitude and latitude - when reading the Tracklogs from the receiving device via a by means of software installed on an external computer unit generates a so-called hash value associated with the read data will be so belated in this way Manipulations become recognizable.

Such systems with precautions against manipulation are used in the context of cross-country flying competitions, especially in gliders or paragliders to documented distances and test flights can. These are special GNSS flight data recorders that are protected against manipulation attacks and actually flown flight path coordinates in one Store storage unit for the purpose of retrieval protected.

Yet remains the problem that, for example, a manipulation of the Data is not recognized, if, for example, data of a fictitious and manipulated tracklogs are uploaded to the device and subsequently added to the Readout available be put.

A Further development of such GNSS loggers concern devices which already inside the device at least one hash value over generate the recorded GNSS tracklog. These devices have the Part in addition to one barometric altimeter and a microphone for detecting engine noise to determine, for example to be able to whether any auxiliary engines during a route sail flight have been activated. Such special for the Air sports developed receivers offer a relatively good Protection against manipulation. Comparable systems for a secured Documentation of sports activities that are in the first place through a route management are currently not available. So For example, a manipulation in cycling can be done by that For example, a cyclist for tackling a route sections motor assisted to complete the route faster. Another possibility for manipulation would in that an unauthorized transfer the corresponding recording unit from one person to one another person takes place, so that ultimately several athletes in succession a route to be mastered complete the only for a single athlete was provided.

Presentation of the invention

Of the Invention is the object of a device and a Method for documenting a characterizable by change of location physical training to develop a person such that the above-described manipulation possibilities full can be revealed or be thwarted from the outset. In particular, it applies a tamper-free documentary aid for both the sports as well as for the therapeutic medical field, in particular for documentation a correct execution physical Rehabilitation measures specify.

The solution the object underlying the invention is specified in claim 1. Subject matter of claim 16 is a solution according to the method for documenting as well as to check one by change of location characterisable physical exercise one person. The idea of solution advantageous further-forming features are the subject of the dependent claims and the further description in particular with reference to the embodiments refer to.

So is a solution according to a device for the documentation of a characterizable by change of location physical training a person with a mobile receiving unit for signals to the geographical Location determination that generates location data, a sensor unit for detection at least one person-specific vital parameter for generation vital signs, a data recording and storage unit, as well as a data processing unit for processing the location and vital data characterized by that in addition an inertial sensor system is provided, the acceleration forces and / or Accelerating moments of the person recorded and acceleration data generated the data recording and storage unit and the Data processing unit can be fed are. The data processing unit also has an encoding unit which the location, vital and / or acceleration data, preferably all encoded data.

So can additionally to the detection and determination of the geographical position of the Person and the detection of at least one vital parameter of Person, in particular the heart or pulse rate, also with the help the inertial or Acceleration sensor attached to a suitable location on the body of Person to be attached, continuously the motion picture or movement pattern the person are recorded and evaluated.

• – Ist eine vorgeschriebene Strecke seitens der Person absolviert worden?
• – Ist die vorgeschriebene Strecke tatsächlich mit dem jeweils vorgeschriebenen Sportgerät bzw. in einer vorgeschriebenen Bewegungsweise bzw. mit einem vorgegebenen Bewegungsmuster absolviert worden?
• – Wurde die vorgegebene Strecke von der jeweils betreffenden Person absolviert?
• – Mit welcher körperlichen Verfassung bzw. Performance in Bezug auf Geschwindigkeit, Beschleunigungen und körperliche Belastung wurde die vorgeschriebene Strecke von der jeweiligen Person absolviert?
• – Wann wurde die jeweils vorgeschriebene Strecke von der Person absolviert?

It is only through the integration or combination of the three sensor types mentioned above that the prerequisite for a forgery-proof evaluation of the collected data is created in order to be able to give reliable statements on the following questions:

• - Has a prescribed distance been completed by the person?
• - Has the prescribed distance actually been completed with the respectively prescribed sports equipment or in a prescribed mode of movement or with a given movement pattern?
• - Has the given distance been completed by the person concerned?
• - With which physical condition or performance in terms of speed, acceleration and physical strain was the prescribed distance completed by the respective person?
• - When was the prescribed route taken by the person?

To encounter a data manipulation, the location, vital and also acceleration data acquired by the sensors during the Recording, z. B. at intervals, for example. Every five seconds, or provided after completion of the recording with a backup or coding, advantageously by forming a checksum by hash value formation by means of a hash or scatter value function. The checksum obtained on the basis of the acquired data is stored together with the data and serves for the subsequent verification of the authenticity of the stored data. As an alternative to hash value formation, it is likewise possible, on account of the digital data structure of the stored data, to generate a digital watermark which can be used in a similar manner as a hash value for a subsequent authenticity check of the data. For this purpose, the respective hash value or the watermark on the acquired data is either quasi-continuously formed during recording at time intervals or calculated on completion of the recording, either automatically or manually initiated by the user over the entire record. In both cases, the data record which is read from the data memory for subsequent data evaluation, be it by means of a transmission cable to an external computer unit or by means of a wireless data transfer eg. Via a mobile network, provided with the respective code, so that a subsequent manipulation can be recognized on the record. The detection of the manipulation is determined by the record to be evaluated is again hashed or watermarked. A comparison of the respectively read hash value or watermark with the respectively subsequently calculated permits an authenticity check. Such a validity or authenticity check ensures detection of manipulation attempts and also ensures that only data sets that have not been subsequently manipulated are included in a further evaluation.

Yet can do a validity check in the above However, only the subsequent manipulation is described in isolation of a data record. Was the record against foul generated, for example, by a prescribed route with covered another sports equipment was when it was prescribed, or by several athletes in a kind of relay race has been completed, this can not reveal the validity test. Rather, a downstream plausibility check of the sensory data.

in the The scope of the plausibility check will be all used by the sensors to check whether a course was completed with a prescribed sports equipment, and the others to verify that for each competition admitted athlete has actually completed the route. For this In a learning process, reference data are collected, on the one hand for the species the respective physical training, eg depending on the respective sports discipline and the sports equipment used in each case for each individual athlete himself.

to Registration of the sports discipline or the sports equipment used Reference data will be both location data, vital and acceleration data which, taken as a whole, provide a kind of fingerprint or "fingerprint" of the physical training or sports equipment represent. It makes sense Sports-specific complementary Sensors taken into account such as cadence sensor data the exercise of cycling. From the receiving unit to determine the geographical Position will be in particular the acceleration and speed values a sports equipment dependent on extracted the respective route profile. From the motion sensor or Acceleration sensor will be typical movement patterns that in the exercise or operating a particular sports equipment typically occur extracted. The additional consideration of vital parameters, such as the heart rate, leave at a combined consideration with the acceleration and velocity values Conclusions on it to whether the respective athlete in the exercise of the sport, for example, a external support has experienced, so can be recognized, for example, whether a cyclist occasionally pulled by a car or motorcycle.

For the collection of reference data relevant to the respective athlete or the respective person, data relating to the geographical position, for example in the form of a track log traveled by the athlete, and the vital parameters of the person that can be detected during the course of a course are essential. The relevant data collection should be carried out with the inclusion of the respective sports equipment, which is to be used for the completion of the respective predetermined route. Based on the reference data, which also correspond to a fingerprint of the respective athlete, it becomes visible which vital parameters are associated with the speed and acceleration data of the respective sports equipment. Although it is hardly possible to deduce an individual athlete from a snapshot of recorded pulse values and the current speed of the sports equipment, a characteristic fingerprint arises from the course of the data and taking into account the route profile, which in all likelihood suggests an individual athlete. The quality of recognition increases as the number of available Da increases taking into account the training progress the athlete experiences over time.

The Evaluation and verification of recorded during sports practice Data is preferably on a conventional computer or a portable minicomputer unit that has an input interface via the preferably by wireless data transmission, for example Bluetooht technology, the data is read. The evaluation unit also has a Verification unit containing the at least one encoded coded Data record containing the location, vitality and / or acceleration data and at least one hash value or watermark, checked for authenticity. For this is a hash generator or watermark generator provided, based on the data read a hash value or generates a watermark, using a comparator with the transferred Hash value or watermark is compared. If the codings are the same, then no manipulation of the data was done, so that the data can be subjected to further investigation. in the The frame of the verification unit is a reference data record memory provided, from the reference data, the respective sport or the used sports equipment as well as characterize the person who are readable with the transferred ones Location, vital and / or acceleration data compared in terms of plausibility become.

To step strong deviations from the reference data, so there Reason to believe that has been worked with unfair means is. Related records may be used accordingly recorded and rejected or a special manual evaluation be subjected.

In addition is it possible a comparison of the data of a respective athlete with the data other athletes who participated in the competition to have. Are there very strong deviations from predefinable tolerance limits of readings within individual records, so can these records excluded from the rating or a detailed manual Inspection supplied become.

On the basis of the means of conventional data processing techniques automatically feasible Validitäts- and plausibility check of the each read records a rating committee has a system available that both the subsequent Manipulation of a record reveals, as well as the manipulation while the record's record open. This is the basis created to organize decentralized sports competitions where none Folder or marshals required for monitoring are. About that also allows The solution according to the data acquisition and verification system a surveillance as well as documentation and proof of the correct execution of a therapeutic measure for the purpose of medical rehabilitation of patients. Such documentation can as proof and proof for a targeted Therapy for the submission and billing with health insurance companies serve.
