In today's world, the personal information of any person can be conventionally divided into two large categories: general and special. As you can understand from the name, the first category is responsible for the type of data that can be found in public access, namely: surname, first name, patronymic, signature, place and date of birth, citizenship, marital status, education, bank details, etc. Such a variety of personal data requires different methods and automated means of storage. Today, private and state institutions increasingly refuse to store information in paper form. This is explained by the low level of security of such storage facilities, which can be affected by fire, water, pests, etc. Information that exists in paper form is very easy to lose, for example, misplaced or lost during movement. It is shown that digital storage of information makes it possible to get rid of such problems. Personal data that is stored electronically can often be recovered even if the device from which it was accessed is lost. One of the main types of personal information in modern society is login data: login and password. That is why the algorithmic and software of the automated system for saving the user's personal data was developed. This system should enable the user to generate passwords resistant to standard hacking methods and store them in the database. The development of the automated system took place using the MVC architectural template, which is one of the options for implementing a multi-level architectural model. For detailed design and coding, an object-oriented Java programming language with static strict typing was chosen. It was also decided to develop an automated system in the form of a web application using the Spring framework. During the development process, a local database was designed, which will store personal data in the form of logins and passwords entered by the user or generated by the system itself. An algorithm for generating hack-resistant passwords has been developed. Hash algorithms are also used as an additional protection of the main password of the web application. A graphical interface has been created that allows the user to access the main functions of the automated system.

“…With the development of cryptographic techniques, many cloud storage data integrity auditing schemes have been proposed [1], [2], [3], [4]. Data integrity auditing schemes are mainly divided into two categories, provable data possession (PDP) [5] and proof of retrievability (POR) [6].…”

To save local storage space and protect data privacy, enterprises store data in the private cloud. The private cloud is only open to internal users of the enterprise, but the data owners lose control over outsourced data, so data integrity auditing is still an urgent problem to be solved in secure cloud storage. Although the existing data integrity auditing schemes on lattices can effectively resist the quantum attack, they lack fine-grained management of user permissions and have key escrow problems. This paper combines attribute-based signature on lattices to construct a revocable attribute-based data integrity auditing scheme on lattices. Firstly, the system master key is generated by using the trapdoor generation algorithm, and then combined with the user's attribute set, the user's initial key is generated by using the lattice extbasis algorithm. Secondly, users add their own identity information and generate real keys without key escrow by using lattice randbasis algorithm. In the data submission stage, the Gauss sampling algorithm and the lattice extbasis algorithm are combined to generate the signature. Moreover, the authorization center periodically updates the revocation list through user identities and attribute sets to implement dynamic management of users. Based on the hardness assumption of SIS problem, it is proved that the scheme has strong unforgeability and storage correctness. Compared with the existing data integrity auditing scheme, the security and practicability are higher.
