Embodiment Construction

[0035] see figure 1 , which is a method flow chart of the first embodiment of the method for encrypting and decrypting a contact phone with a SIM card according to the present invention.

[0036] In order to achieve the above object, the SIM card contact phone encryption and decryption application method of the present invention, the method first embodiment comprises the following steps: display operation interface, wait for the user to select for encrypted storage or decrypt and read the input of selection or password (step 100 ); read encrypted storage selection or decryption read selection or password (step 101); read encrypted storage sign and decryption read sign (step 102) in the registry; judge whether encrypted storage sign changes (step 103); when above-mentioned Be judged as " yes ", revise registry encryption and store sign (step 104); Put modification sign (step 105); Judge whether the decryption read sign changes (step 106); When above-mentioned judgment is " yes ...

Abstract

This method includes: (1) Display the operation interface and waits for the user to access; (2) Read the encryption storage selection, the decryption reading selection and the password (PW). (3) Read the encryption storage sign (ESS) and the decryption reading sign (DRS) in the register table (RT). (4) Judge whether ESS needs to change. If it does, modify ESS in RT and set modifying sign (MS). (5) Judge whether DRS needs to change. If it does, modify DRS of RT. (6) Judge whether MS is not set. If it is not set, set MS. (7) Judge whether PW is not empty. If it is not empty, encrypt PW and write PW into RT. (8) Judge whether MS is still not set. If it is not set, set MS. (9) Judge whether MS is set. If it is, write MS into RT. Use this method, the contact phone number will not leak even if SIM card is lost.

Description

【Technical field】 [0001] The invention relates to an encryption application and an encryption and decryption driving method, in particular to an encryption and decryption application and a driving method for a SIM card contact phone. 【Background technique】 [0002] The phone number of each contact stored in the SIM card is private information for the user, and it is still very important information for many people, especially for those special and important people, it cannot be Randomly disclosed to unrelated people. Therefore, it is important to provide a confidential function to the contact number. However, as an indispensable contact method now, the phone number needs to be disclosed to some people. [0003] In view of this, it is necessary to provide a SIM card contact phone encryption and decryption application and driving method, which provides a feasible way to solve this contradiction. The present invention provides an encryption protection function for contact nu...
