Hardware encryption storage method and system for mobile phone private contacts

Abstract

The invention discloses a hardware encryption storage method of mobile phone private contacts. The hardware encryption storage method comprises the following steps of passing a safety certificate process, using the IMEI number of an ID card and an SIM card and the SN number of a storage chip of mobile phone equipment as parameters to generate a secret key for encryption and decryption, leading in contact information and storing the information into a temporary database file, using an encryption and decryption module to encrypt the temporary database file, and the data of the encryption contacts are stored into an Eflash storage area in an encryption storage chip. The invention further provides a decryption display method corresponding to the encryption storage method and a hardware encryption storage system. According to the hardware encryption storage method and system of the mobile phone private contacts, system sources are not occupied, high performance, high safety and high reliability are achieved, and the demands for encryption protection of private communications or contacts of people can be effectively met.

Description

technical field [0001] The invention is applied in the fields of mobile communication, information security, etc., and in particular relates to a high-performance, high-safety hardware encryption storage method and system for mobile phone private contacts. Background technique [0002] Through investigation, at present, there is no mobile phone in the market that directly encrypts and stores private contacts, and there is no mobile phone product that uses hardware encryption storage chips for data protection. At present, there are some software applications in the software market that can add designated system contacts. as a private contact. After adding a private contact, the incoming call records and text messages of this contact will be stored in a separate database, and the relevant communication content of the private contact cannot be seen in the system call records and text messages, only after login and authentication to the privacy protection interface Only then ca...

Problems solved by technology

Since the private contacts are not processed, some software saves the private contacts in a local database separately, but they still exist in the system contacts, and some will delete the private contacts in the system contacts, no matter what kind of storage By exposing the private contacts to the system, the database can be obtained, and the private contact information can be viewed. The system’s misoperation may also delete the stored contact information, and thus come from this technology or method. In other words, both security and reliability are facing deficiencies
