Motion data encryption transmission method and motion recorder

Abstract

The invention provides a motion data encryption transmission method and a motion recorder. The method comprises the following steps that: the motion recorder receives data of a mobile phone network through a built-in subscriber identity module (SIM) card; a special module analyzes the data and intercepts effective information serving as a secret key from the data; the secret key is written on a special data address of the special module through a private instruction; the special module acquires health data from a motion state record module and encrypts the health data by the secret key on thespecial data address; and the encrypted health data is sent by the SIM card. By the motion data encryption transmission method, small equipment has an encryption system in a finance level, manpower and financial resources are saved, and the safety of data transmission is not reduced.

Description

technical field [0001] The invention relates to a method for encrypted transmission of motion data in the field of telecommunications and a motion recorder using the method for data transmission. Background technique [0002] The Subscriber Identity Model used in mobile communication technology, referred to as SIM card, is widely used as a subscriber identification device for mobile communication terminals. With the development of science and technology, various intelligent circuit modules are added to the SIM card body of ordinary mobile communication terminals through various methods, so that in addition to the basic SIM card functions, the transformed SIM card has other functions that are closer to the SIM card. Life functions, such as radio frequency SIM cards, but this transformation is limited by the operator, and the subsequent promotion also needs the platform of the operator, in addition to the support of professional SIM hardware manufacturers. After years of deve...

[0003] At present, there are sports recorders with built-in SIM cards on the market, which transmit health data through the wireless data transmission channel of the SIM card communication module. However, with more and more functions of sports recorders, different types of health data will be integrated. Health data is becoming more and more private, so the security of data transmission is becoming more and more important. The best way to ensure the security of data transmission is to use a dynamic key system

However, except for products with financial functions that have a key system (including pre-saved keys, encryption and decryption, and key updates), other products do not have similar functions. Due to the high level of security requirements of financial products, encryption at all levels Different keys and encryption methods are different. The hardware needs to set up a special department to manage, and the software needs a special independent module to run, so as to ensure the safe and stable operation of financial products. No matter in terms of manpower and financial resources, small devices are not suitable for such a large management
