The invention has the following advantages:
in the invention the first terminal sends the generated two-dimensional code of a product to a second terminal and sets the two-dimensional code in the electronic tag of the product, so that the second terminal can read the two-dimensional code in the electronic tag of the product and authenticates it according to the previously stored two-dimensional code. Based on this, if a user is not from the second terminal or a product doesn't belong to the user at the first terminal, then the two-dimensional code at the second terminal will be incorrect or the two-dimensional code in the electronic tag of the product will be incorrect, and thus the authentication can not be achieved and the electronic tag will not change colors. From this, as compared with the prior art, the identity authentication of users at two terminals is achieved.
In order to illustrate more clearly the technical solutions of the embodiments of the invention, the drawings used in the embodiments will be described simply hereinafter. Obviously, the drawings are given only by way of example, and for a person skilled in the art, other equivalent drawings can be obtained according to these drawings without any creative work.
In order to make the object, technical solutions and advantages of the invention more clearly, the technical solutions of the embodiments of the invention will be described hereinafter fully and clearly in connection with drawings. It is obvious, that the embodiments to be described just are parts of the embodiments of the invention, instead of all of the embodiments. Based on the embodiments of the invention, the other embodiments obtained by one skilled in the art without any creative work are covered by the protection scope of the invention.
The core of the invention is in that: a two-dimensional code of a product generated by a first terminal is not only sent to a second terminal, but also is set in an electronic tag of the product. After receiving the product, a second user obtains the two-dimensional code in the electronic tag of the product by means of the second terminal and authenticates it according to the previously stored two-dimensional code. If authentication is successful, then the second terminal sends an instruction to activate the electronic tag such that it changes colors.
The above process can be applied in various situations. Taking a merchant and a customer as example, after a purchase agreement is reached, a two-dimensional code of goods is generated by the merchant by means of a first terminal, and the two-dimensional code is not only sent to the customer at the second terminal, but also is set in an electronic tag of the goods, then the goods will be transported to the customer by a logistics company. After receiving the goods, the customer obtains the two-dimensional code in the electronic tag by means of the second terminal and authenticates according to the two-dimensional code sent from the first terminal. If authentication is successful, the second terminal sends an instruction to activate the electronic tag such that it change colors. Based on this, if the customer is an illegal user, i.e., an unreal buyer, then the two-dimensional code at the second terminal is false, and will not match with the two-dimensional in the electronic tag. Similarly, if a merchant is not the specified merchant, then the two-dimensional code in the electronic tag is false, and will not match with the two-dimensional code at the second terminal, and thus the electronic tag will not be activated to change colors. From this, in the above process identify authentication is achieved for the merchant and the customer. In the case of current prevailing online shopping, the security of transaction is greatly improved. Furthermore, the results of authentication can be intuitively displayed by means of the color change of electronic tag.
As shown in
S11, a first terminal generating a two-dimensional code of a product, and sending the two-dimensional code to a second terminal and providing the two-dimensional code in an electronic tag of the product. Specifically, the first terminal generates the two-dimensional code of the product according to identification information of a second user and product information, the second user is corresponding to the second terminal, such as the above customer.
When this method is applied between a merchant and a customer, the first terminal also may further generate a two-dimensional code in combination with purchasing information and merchant information.
S12, the second terminal reading the two-dimensional code in the electronic tag, and authenticating the electronic tag according to the two-dimensional code sent from the first terminal.
S13, the second terminal sending an activation instruction to the electronic tag if authentication is successful.
S14, the electronic tag changing colors according to the activation instruction.
In order to further improve the security, before the step of S11, the method also comprises:
S10, the first terminal obtaining the biological information of the second user and generating a first key according to the biological information of the second user, the second terminal obtaining biological information of a first user and generating a second key according to the biological information of the first user, wherein the first user is corresponding to the first terminal and the first key is corresponding to the second key.
Now the step of S11 specifically is: the first terminal generates the two-dimensional code of the product according to the first key and the product information, and sends the two-dimensional code to the second terminal and provides the two-dimensional code in the electronic tag of the product.
At this moment the step S12 specifically is: the second terminal reads the two-dimensional code in the electronic tag, and authenticates the two-dimensional code in the electronic tag according to the two-dimensional code obtained from the first terminal and the second key. Specifically, firstly the two-dimensional code in the electronic tag is authenticated by means of the two-dimensional code obtained from the first terminal, and after the product information and first key is obtained, the first key is authenticated according to the second key.
For example, the merchant and the customer can exchange their biological information such as respective fingerprint using a same platform. Then, the first terminal of the merchant achieves the generation and matching of keys according to the obtained biological information. The merchant generates a two-dimensional code in combination with merchant information, purchasing information and the key generated according to the biological information of the customer, and sends the two-dimensional code to the second terminal and sets it in an electronic tag. After reading the two-dimensional code of the electronic tag, the second terminal will achieve authentication according to the previously obtained two-dimensional code to obtain the corresponding merchandise information, purchasing information and a key. Then the second terminal matches the stored key corresponding to the merchant biological information with the key in the electronic tag. If they match with each other, then the authentication is successful, and then the second terminal will send an activation instruction to the electronic tag such that it changes colors hereby.
Referring to

The above battery 14 can maintain the power for activating color change.
It is noted that, the electronic tag of the invention can be designed so that it is invalid and can not change colors after one-time activation. Specifically, the battery can be set such that it's power only can maintain one-time color change, or alternatively the receiving times of the activation instruction are determined by the control chip, if receiving for the first time, the conversion command is sent to the converting unit, otherwise the conversion command will not be sent to the converting unit.
