At First, to the letter digital security system introduced

Digital security system to the letter of inquiry system is mainly enterprise customers product data set, generated security code, security code management, information storage and management, the user can through the Internet, telephone, mobile phone text messages three ways to check certification.

The system is simple, low cost, safety, suitable for major small and medium enterprises so that enterprises easily have their own proprietary security systems. Truly escort for their own products!

To the letter digital security system structure is as follows:

The Second, the main technical advantages Introduction

Currently on the market mainly in the following ways digital security

The first: the random code stored directly in the database or by encryption stored in the database query the database directly query result. This approach is simple, and can implement all the features of digital security. But in the actual process, database storage capacity, query and processing speed, data backup difficult, requiring high computer and network hardware configuration, poor data security features, to the letter in 2004, has been abandoned in this way;

      The second: the use of a password table combined into a security code, this approach requires low computer network configuration, data is saved by a password table, using a simple database access can be achieved. Because the password table is a combination of a certain order, once the password table is compromised, it is easy for someone else to break.

      To the letter digital security system platform is based on the above two security systems from developed, through a password table, sequence control table, the encryption algorithm combination of the three. The lack of any one can not produce security code and implement the query security code.

      To the letter digital security system platform in addition to strict compliance with the main features of digital security, but also has the following advantages:

     1. The security of data is absolutely safe, password table, sequence control table, three indispensable encryption algorithm;

     2. The data storage capacity is small, only a password table, sequence control table stored in the data system for stable operation and system query speed provides the foundation.

     3. The security code be manageable, can achieve with interfaces to other systems, such as anti-channeling management, shipping management, to achieve a combination of both.
