specific Embodiment approach 1

[0029] Specific Embodiment 1: The block chain-based card reader reading permission verification method described in this embodiment requires a verification terminal (ie: a PC connected to the card reader), a card reader, The smart card, the upper-level system, the block chain and the various block chain servers that make up the block chain participate in the completion. As a node that makes up the blockchain, the blockchain server realizes data interaction with the verification terminal. The upper-level system has the authority to approve the card reader information, and can give the card reader permission to read the information in the smart card and complete the data interaction with the verification terminal.

[0030] Specifically, the above method includes the following steps:

[0031] Step 1: Use the current verification terminal to collect the information of the card reader to be verified, the information includes the current card reading time, and the current verificat...

Abstract

The invention discloses a card reader reading permission verification method based on a block chain, and relates to the field of card reader safety card reading. The method aims to solve the problemsthat the internal module is complex and the safety degree is low due to the fact that a safety module is embedded in an existing card reader. According to the card reader reading permission verification method based on the block chain, an authentication certificate capable of confirming the reading permission is stored in the block chain in combination with a block chain technology, so that the authentication certificate is not easily tamper, and the security is enhanced. Meanwhile, even if the data of one block chain server side is damaged, the other block chain server sides in the block chain can be requested to obtain the verification data, that is, the data of the verification permission cannot be lost, and the reliability is further enhanced. Moreover, the verification information isstored in the block chain, and a security module does not need to be additionally arranged in the card reader, so that the module structure of the card reader is simplified.

Description

technical field [0001] The invention belongs to the field of safe card reading by a card reader. Background technique [0002] A smart card reader is a device with one or more connectors connected to a PC and receives instructions from the PC to operate a smart card or security module in each connector. The smart card reader is mainly used to obtain, modify or store relevant data in the smart card. Smart card readers are mostly used in hospitals, banks, transportation, hotels, social security, telecommunications and other industries. Some sensitive data will be involved in these industries, so most of them have higher requirements for information security. In application, smart cards that involve sensitive data need to be encrypted and decrypted with their corresponding security modules to obtain operation authority or plaintext data. For example, social security applications have security modules with social security specifications, banking applications have security modul...
