A method for encrypted storage of telephone numbers

Abstract

The invention discloses a telephone number encryption storage method, which dynamically creates a KEY and creates a letter comparison set; performs md5 encryption on the KEY to intercept the first 10 character strings; performs an ascii code value for each character to form a decimal array, and successively converts the letters Take the remainder of the comparison set to obtain the p value, obtain the letter in the corresponding position of the letter comparison set, delete this letter as a new letter comparison set, repeat until the letter comparison table of 0-9 is obtained, and then compare the phone number according to the letter The comparison table is replaced and stored one by one. The invention dynamically creates a KEY for the mobile phone number sensitive information in the database, generates a 0-9 letter comparison table through the KEY, and then replaces and stores the phone number one by one according to the letter comparison table, so as to achieve the effect of encryption and avoid leakage of sensitive data; When searching for a phone number, use the same method to replace and retrieve the phone numbers to be searched one by one, so as to achieve the purpose of fast retrieval.

Description

A method of encrypting and storing telephone numbers technical field [0001] The present invention relates to the technical field of information security, and in particular, is a method for encrypting and storing telephone numbers. Background technique Prior art has carried out direct storage to telephone number, to the mobile phone number that user submits, directly created a A field is used for content storage, and the stored content is consistent with the user's actual mobile phone number information; Or once the database is breached, the user's phone number data will be leaked. In the prior art, there are also transmissions such as md5 etc. It is stored by traditional encryption method, but it is not convenient for data search, and cannot achieve the purpose of fast matching or query. SUMMARY OF THE INVENTION The object of the present invention is to provide a kind of telephone number encryption storage method, for solving the telephone number in the prior art ...
