Tampering prevention refers to adopting technical means or management system to ensure that the information or content of a system or a document cannot be tampered with at will. This is an important means to maintain data security and ensure the authenticity of information. Tampering has been widely used in today's information society, including finance, e-commerce, government affairs and many other fields.

there are two main ways to prevent tampering. The first method is to encrypt the original data through cryptography and check the validity of the encrypted data to determine whether the data has been tampered with. The second is to use digital signature technology to digitally sign the data, and to ensure the integrity and authenticity of the data through public key cryptography or hash algorithm.

Anti-tampering plays an indispensable role in protecting data security and information authenticity. Once data and documents are tampered with, it will bring many risks to all aspects, such as financial fraud and intellectual property infringement, which will have a serious impact on social stability and the healthy development of various industries. Therefore, the application and popularization of tamper prevention in various fields is very important, which is helpful to ensure information security and social stability.
