Description

Label information identification method

Technical Field

The invention relates to a tag information identification method, in particular to a method for generating a communication encryption key by using application ID information capable of uniquely identifying the identity of a user at a wechat applet client, and encrypting and decrypting communication between the wechat applet client and tag equipment, so that the tag identification safety and the user use convenience are improved.

Background

With the development of information technology and the popularization of mobile internet, various intelligent terminal devices, particularly smart phones, are more and more widely applied, and great convenience is brought to the daily life of people.

The object searching is a thing which people often encounter in daily life. People may forget the last place of the article for their own use when needed due to various reasons, so that it takes a lot of time to search for the article, and even the article cannot be found at any time, which may cause some influence on work or life.

The electronic tag capable of being identified by the smart phone is installed on the article, the electronic tag sends information representing the characteristics of the article to the outside through wireless signals, when a person forgets the last placement position of the article, the wireless signals sent by the peripheral tags can be received only by opening the mobile phone, and therefore the tags are judged to be in a certain peripheral range. Furthermore, through the sound/light/electric module arranged in the tag, when the mobile phone finds that the tag is located at the peripheral position, the mobile phone can control the tag to send out sound/light/electric signals through wireless signals, and a user is helped to quickly find an article bound with the tag.

The low-power consumption Bluetooth technology is a wireless communication technology which is very popular in the current smart phones and has the characteristics of low power consumption and low cost. WeChat is one of the most popular application software on smart phones in China, and the number of users in China exceeds 10 hundred million. Therefore, a set of tag information identification system is realized based on the WeChat small program and the low-power-consumption Bluetooth technology, is used for finding and positioning articles in daily life of people, and has an extremely low user use threshold and a wide use scene. However, in the specific implementation process of the above technical solution, the following engineering problems need to be solved to achieve better user experience:

1. due to the popularization of Bluetooth equipment, when a small program client scans peripheral Bluetooth equipment, a plurality of Bluetooth equipment signals irrelevant to a wechat user can be searched, and the user needs to manually distinguish the signals, so that the user experience is poor;

2. many times, personal articles belong to the personal privacy category, and users do not want others to search personal articles;

therefore, how to quickly and safely help users find personal articles which only belong to the users is a problem which needs to be solved. Wechat is used as a mobile application program for real-name authentication, and has user identity uniqueness. The WeChat applet client user application ID generated based on the unique user identity is also unique, and when the WeChat applet client user application ID is used for configuration of a tag and encryption of communication data, association of the tag equipment and the WeChat personal identity can be achieved simply, conveniently and safely, and therefore convenience and safety in the identification process of the personal tag equipment are improved.
