TL;DR: A new security primitive based on hard AI problems is presented, namely, a novel family of graphical password systems built on top of Captcha technology, which is called Captcha as graphical passwords (CaRP).
Abstract: The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, user tends to pick passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. In this paper, we present a new security primitive based on hard AI problems, namely, a novel family of graphical password systems built on top of Captcha technology, which we call Captcha as graphical passwords (CaRP).
Key Words— Graphical password; password; hotspots; CaRP; Captcha; dictionary attack; password guessing attack; security primitive

TL;DR: This paper and presentation shows relatively simply code to perform typical “look-up” match-merge usage as well as a method of using the hash object to add or remove records.
Abstract: The purpose of this paper and presentation is to introduce the basics of what a hash table is and to illustrate practical applications of this powerful Base-SAS DATA Step construct. We will highlight features of the hash object and show examples of how these features can improve programmer productivity and system performance of table lookup and sort operations. We will show relatively simply code to perform typical “look-up” match-merge usage as well as a method of using the hash object to add or remove records.

TL;DR: This paper proposes to use the commonly used Miller-Rabin prime number detection algorithm to generate random large prime salt to resist the attack of rainbow table and proves that this method plays an important role in the secure storage of blockchain data.
Abstract: Blockchain technology is now a frontier field of high value with its unique technological advantages, innovative value concepts and wide application scenarios. The blockchain guarantees the integrity and anti-tamper modification of the stored transaction data through the hash algorithm. In the face of the hash algorithm, the centralized attack method, namely the brute force cracking method, the dictionary cracking method and the rainbow table attack method, is realized by using the collision principle. Based on the traditional method of salt-adding hashing, this paper proposes to use the commonly used Miller-Rabin prime number detection algorithm to generate random large prime salt to resist the attack of rainbow table. The test time comparison proves that this method plays an important role in the secure storage of blockchain data.

TL;DR: In this paper, a multiple hash value password system was proposed, where multiple values (or strings) are generated via a certain one-way algorithm from a user password, respectively for use in different purposes.
Abstract: Multiple hash value password system that is: multiple values (or strings) are generated via a certain one-way algorithm from a user password, respectively for use in different purposes. The user password is encrypted, decrypted, and restored by means of question answering. In a case that a server has no knowledge of the user password and data content, this implements the provision of a service to a user and facilitation of user privacy protection.
