Method, apparatus, and system of detecting data security

An apparatus of detecting data security, comprising:

• an acquiring unit configured to acquire data for detection, wherein the data for detection include data that need a security detection and that need to be updated;
• a determining unit configured to determine whether the data for detection are to be updated for a first time;
• a first processing unit configured, after determining that the data for detection are to be updated for the first time, to update the data for detection, to obtain the updated data for detection, to encrypt the updated data for detection to provide first encrypted data, and to save the first encrypted data;
• and
• a second processing unit configured, after determining that the data for detection are not to be updated for the first time, to acquire an original value of the data for detection, to encrypt the original value to provide second encrypted data, to acquire the stored first encrypted data, and to determine that the data for detection have been unauthorizedly modified, after determining that the second encrypted data do not equal to the first encrypted data.

A non-transitory computer-readable medium having computer program for, when being executed by a processor, performing a method of detecting data security, the method comprising:

• acquiring data for detection, wherein the data for detection include data that need a security detection and that need to be updated;
• determining whether the data for detection are to be updated for a first time;
• and
• when the data for detection are to be updated for the first time,
• updating the data for detection,
• obtaining the updated data for detection,
• encrypting the updated data for detection to provide first encrypted data, and
• storing the first encrypted data;
• or
• when the data for detection are not to be updated for the first time,
• acquiring an original value of the data for detection,
• encrypting the original value to provide second encrypted data,
• acquiring the stored first encrypted data, and
• determining that the data for detection have been unauthorizedly modified, after
• determining that the second encrypted data do not equal to the first encrypted data.
