detailed description

In order to solve the following problems in the prior art: more and more cases are completed by the signature on the smart terminal, and once the user signature is counterfeited, the user is caused a certain loss; the present disclosure provides a signature recognition method. The device, the mobile terminal, and the cloud server are further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to be limiting.

The first embodiment of the present disclosure provides a method for identifying a signature. The process of the method is as shown in FIG. 1 and includes steps S102 to S106:

S102. Receive signature information. When the user performs payment or other operations on the mobile terminal side, if the signature is made, the terminal receives the signature information.

S104: Match the signature information with a preset signature obtained from the cloud server. After the signature information is obtained, the matching degree between the signature information and the preset signature is determined, and it is determined whether the matching degree reaches a preset matching degree. In the process of implementation, from a security perspective, the default signature is stored in the cloud server.

S106. Determine that the signature information is a real signature if the matching degree reaches a preset matching degree. The preset matching degree can be set as high as possible according to requirements. For example, when the similarity reaches 95%, the signature information is not forged signature. Of course, the preset matching degree can be set by the user, and thus, for some fear A troublesome user will reduce the preset matching degree, and for some users who want higher security, the preset matching degree can be improved. The process of letting the user set the preset matching degree autonomously can improve the user experience.

The embodiment of the present disclosure acquires a preset signature from the cloud server. The preset signature is saved in the cloud server and is not easily stolen. When the user inputs the signature, the received signature information is compared with the preset signature to determine whether the signature information is The real signature, the method can easily identify the case of forged signature, and the user experience is high, which solves the following problems in the prior art: more and more cases are completed by the signature on the smart terminal, and once the user signature is counterfeited, It will cause some loss to the user.

For the execution body of the foregoing process, the embodiment may be implemented on the mobile terminal side, that is, the mobile terminal as a main body to determine whether the matching degree reaches a preset matching degree. Certainly, in some cases, the embodiment may also be implemented on the cloud server side, that is, the cloud server itself obtains a preset signature from itself, and matches the preset signature with the user signature information, that is, the entire process is performed by the cloud. The server does.

When the current signature information of the user is obtained, the OCR technology may be used to scan whether the signature information exists or not, and in the case where the signature information exists, the signature information is recognized.

Before the signature information is matched with the preset signature obtained from the cloud server, the signature information needs to be sent to the cloud server, so that the cloud server searches for the corresponding preset signature according to the signature information. Under normal circumstances, there are two situations in the cloud server, that is, the case where there is a preset signature and the case where there is no preset signature.

In the case that the cloud server has a preset signature, the preset signature found by the cloud server may be received. In the case that the cloud server does not have a preset signature, the user may send a prompt message for setting a preset signature to allow the user to set a preset signature, and then receive the preset signature set by the user, and store the preset signature in the In the cloud server.

In the implementation, the method for determining whether there is a preset signature includes multiple, one of which is to determine whether the preset signature fed back by the cloud server is received within a predetermined time; if the preset signature is not received within the predetermined time, the system can confirm Cloud If there is no preset signature in the server, the user can send a prompt message that the preset signature cannot be found. Then, the user can send a prompt message for setting a preset signature to the user to let the user set the preset signature.

For example, a series of initialization operations to be performed before the user turns on the device, and some prompt messages given to the user after the method takes effect. For example, after turning on the device, enter a percentage range of acceptable errors. If it is between this range, after the end of the scan comparison, the pass is given and the user is prompted with the value of the error.

The scanning module 404 is responsible for scanning the information signed by the user and uploading it to the cloud server.

The setting module 406 is mainly used for setting a user-defined time, and a maximum time value when the query verifies that the condition is met or the condition is not met.

The determining module 408: the main user data signature is in the process of performing verification, and determines whether the original signature of the user is saved in a large database in the cloud.

S805, enable the default duration for comparison verification.

S806. Determine whether the user signature information matches the preset signature of the cloud server. If yes, execute S808, otherwise execute S807.

S807, reminding the user that the data does not match and terminates the transaction.

S808, reminding the user that the data matches and the transaction is safe.

S809, the process ends.

During the implementation process, if the cloud server does not have a preset signature, the user may be prompted to set a preset signature.

For the above technology, the massive signature data information stored on the cloud server can be replaced by the local database technology. However, under the current conditions of cloud and big data, it is not recommended to use the local method to save the database.

The embodiment of the present disclosure utilizes the mobile terminal technology in combination with the cloud big data server to identify the true and false information of the user signing information, so as to prevent more and more property losses in the current society due to theft of the user signature, and fundamentally solve the user's Signature security problem, the technical solution does not need to modify and upgrade the hardware of the existing mobile terminal, so it is very beneficial for rapid application and promotion, and can greatly improve the user experience.
