In the evening of April 2, Beijing time, the US patent and Trademark Office (PTO) granted apple a new patent on Tuesday. Through the patent technology, when the user enters the wrong password, it can be judged whether it is the user's misoperation or the illegal intrusion of others.
The name of this patent is' technology of security intensity analysis through the failure login of intruder '. Through this technology, when the login failure occurs, the system can automatically strengthen the security measures. This technology can be used in server, data center, intranet and other fields, as well as other platforms, such as wireless and wired networks.
The application of this technology is not cumbersome. For example, the technology is used in the enterprise security network. When users access the network, they usually need authentication, such as token or other authentication methods. When there is invalid or failed authentication, the system will analyze the authentication information obtained from the above authentication service to determine whether the operation is the wrong operation of authorized users or the malicious behavior of illegal intruders.
Because users sometimes forget part of their passwords or press the wrong key, Apple's technology preset a 'threshold' range to determine whether the failed attempt will be handled. For example, this technology can obtain an identifier from the failed verification and compare it with the currently valid identification certificate. If the difference between the two is within the threshold, the security verification will not be strengthened, otherwise corresponding strengthening measures will be taken.
One of the necessary steps is to record invalid login operations, in which the enabled counter counts the number of times the wrong password is used. Apple filed a patent application for the technology in 2007, and the inventors were Srinivas vedula and Cameron Craig Morris.
