本发明涉及电子标签，特别是电子标签系统及其压缩及加密方法。The invention relates to an electronic label, especially an electronic label system and its compression and encryption method.
【背景技术】【Background technique】
电子标签与读写装置之间通过耦合元件实现射频信号的空间耦合，在耦合通道内，根据时序关系，实现能量的传递和数据交换。最基本的电子标签系统由电子标签、读写装置与天线三部分组成。电子标签具有唯一的电子编码，有用户可写入的存储空间，附着在物体上标识目标对象。The spatial coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reading and writing device, and in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. The most basic electronic tag system consists of three parts: electronic tags, read-write devices and antennas. The electronic tag has a unique electronic code, has user-writable storage space, and is attached to the object to identify the target object.
目前，电子标签的存储空间比较有限，不紧凑的存储方案不仅造成了稀缺的存储空间的浪费，会造成电子标签的存储容量不能满足应用的需要；另外，电子标签的写操能够实现数据写的安全，但是数据的读取是开放的，可以随意读取，这使得用户的隐私数据不能得到有效的保护。At present, the storage space of electronic tags is relatively limited, and the non-compact storage scheme not only causes the waste of scarce storage space, but also causes the storage capacity of electronic tags to fail to meet the needs of applications; in addition, the writing operation of electronic tags can realize data writing. Safe, but the reading of data is open and can be read at will, which prevents the user's private data from being effectively protected.
