Embodiment 1

[0029] The inventor of this case proposes that the encrypted font content can be stored in a non-updatable manner, so that during the transaction process, the electronic signature device searches the decrypted font file for the characters corresponding to the transaction-sensitive information to be displayed in a table look-up manner. Afterwards, the found characters are encrypted and displayed, thereby greatly improving the security of the electronic signature device.

[0030] Based on the above ideas, this embodiment provides a method for processing transaction sensitive information, including the following operations:

[0031] The online banking client running on the PC or smart terminal device sends the transaction message encoding information, and the electronic signature device receives the transaction message encoding information and extracts the transaction sensitive information that needs to be displayed;

[0032] The electronic signature device decrypts the pre-encry...

Embodiment 2

[0076] This embodiment provides a transaction sensitive information processing device, its structure is as follows image 3 As shown, it includes at least the following three units:

[0077] The first unit extracts transaction sensitive information from the received transaction message encoding information;

[0078] The second unit decrypts the encrypted font file according to a preset decryption method, and then searches for the character corresponding to the transaction sensitive information from the decrypted font file;

[0079] The third unit encrypts and displays the found characters.

[0080] Specifically, the above-mentioned second unit, the process of finding the characters corresponding to the transaction-sensitive information from the decrypted font file is to first perform binary conversion on the characters of the transaction-sensitive information, and convert the internal code of the character to be displayed into For the location code, it is sufficient to searc...

Abstract

The invention discloses a processing method and device for transaction sensitive information and relates to the field of electronic technology application. The processing method comprises that an electronic signature device extracts the transaction sensitive information from received transaction message encoding information; the electronic signature device decrypts encrypted matrix files according to a preset decryption method and finds characters corresponding to the transaction sensitive information from the decrypted matrix files; the electronic signature device encrypts and displays the found characters. The transaction sensitive information at least comprises transaction amounts and account information. By the aid of the processing method and device, the safety of the electronic signature device is greatly improved.

Description

technical field [0001] The present invention relates to the application field of electronic technology, in particular to a processing method and processing device for sensitive transaction information. Background technique [0002] At present, electronic signature tools are more and more widely used in computer, Internet and mobile Internet technology applications, especially in the financial industry. In order to ensure the security of transactions, online banking users are increasingly using electronic signature tools, such as USB Key, As a means of identity authentication and transaction authentication. However, with the continuous escalation of network attacks, in order to better improve the security of online banking clients, strengthen the ability of online banking systems to resist attacks, protect the vital interests of banks, and provide users with convenient, flexible and safe online banking platform services, people A new generation of electronic signature equipm...
