Different types of locks indicate whether the current user permits or prevents other users from simultaneously accessing the same resource, so as to ensure that the system data integrity, consistency, and parallelism are not damaged.

Classes.dex is basically responsible for all the logic business on Android, so many of the tampering with Android apps is for Classes.dex files. In the APK self-protection, you can also consider the Classes.dex file integrity check, simple can be done by CRC check, you can also examine the hash value. Because it's just checking for Classes.dex, you can store the CRC value in a string resource file, or you can put it on your own server.Gets the checksu

"Integrity" is a true portrayal of all our actions in the development process. It is like whether a person can be recognized by people around him or recognized by his friends. Is it true that he complies with the basic morality of "integrity, whether a company's behaviors can be recognized by the society and recognized by users also test the

ObjectiveWhen the server is attacked by hackers, in most cases, hackers may modify some important files, such as system files, and so on. In this respect, we use tripwire to establish data integrity monitoring system. Although it can not protect against hacker attacks and hackers on some important files, but the change is able to monitor whether the file has been modified and which files have been modified, so that the attack after the targeted plan t
damage to the public brand. It takes a long, long time to recover from this kind of injury.If it is because of some technical shortcomings, the public has to recall diesel vehicles, I believe that few people will be concerned. However, because the normal emissions do not reach the environmental standards, the use of cheating means to ensure that the detection of muddle, after testing unchanged. It was a very serious fraud, and even the dead-loyal God-cart party was hard to accept.From the techn
1. Overview of completeness metrics
The runtime's system integrity is guaranteed by the system's access control mechanisms, such as DAC (Discrete access control, indirect access controls)/mac (Mandatory access control, mandatory access controls, such as SELinux, Smack).
DAC/MAC cannot detect offline modification of files, Encrypting File System can protect illegal access, but it is expensive and relatively inefficient.

Integrity constraints are imposed on fields to meet the specific requirements for operations on this attribute.
In layman's terms, if your data does not meet the requirements of my field, the database system rejects the operation.

Solution to integrity conflict when updating primary key values restricted by foreign keys in Oracle stored procedures1. Background
Although we do not advocate modifying the primary key in database operations, there is indeed such a business demand in real life:
Table A has A primary key KA, and table B declares A foreign key constraint for references A (KA). We need to modify the value of KA for an entry in Table A and update the foreign key constrai
