Provided are a method, apparatus, and computer-readable recording medium for authenticating a user. The user authentication method includes scanning a face by operating a camera to obtain a scanned facial image, and comparing the scanned facial image with a facial image registered in a storage. Even if the scanned facial image is mismatched to the registered facial image, a password/pattern is requested. If an input password/pattern matches a registered password/pattern, a device can be unlocked. Additionally, the scanned facial image in the storage may be updated.

The method comprises the following steps: when the server receives a data stream acquisition request for a target data service sent by a user terminal, generating a to-be-verified blockchain for a verification strategy of a specific target data service, so the difference of differentdata services is considered, and the security and the pertinence of the authentication process are improved; enabling the user terminal to calculate the to-be-verified field according to the blockchain generation field in the to-be-verified block chain to generate a corresponding verification field, wherein because the fields to be verified are randomly added, and the difficulty of cracking by a hacker can be improved; performing lawful state detection after the verification blockchain is formed, allowing the user terminal to access the data stream address of the target data service after thedetection is passed, and repeatedly performing verification by monitoring the access information of the user terminal in real time during the period, so the authentication success rate and the security are further improved.

The method sets up general authentication information in GGSN and authentication server in advance. The method also includes following steps: after receiving PDP request message for activating context, based on general authentication information setup in GGSN, GGSN sends out message for requesting authentication including general authentication information to authentication server; after receiving message for requesting authentication, the authentication server determines validity of the general authentication information, and then returns back successful message of request to GGSN. The invention sets up general authentication information in GGSN and authentication server. The said general information is included in message of request sent by GGSN to the authentication server. Thus, success ratio of authentication is increased greatly so as to raise satisfying degree and increase earning of operation manager.

The invention relates to the technical field of information safety, and provides a Beidou second-generation navigation message digital signature anti-cheating scheme based on domestic passwords.

The invention discloses a serial authentication method of a mobile terminal in a WCDMA network. The network side sends an authentication request to the mobile terminal through a PS domain or a CS domain. If a first network parameter equals a first local parameter, a USIM card judges a second network parameter and a second local parameter according to a synchronization check rule. If checking is passed, the mobile terminal sends an authentication success message to the network side. If checking fails, the mobile terminal replies an authentication failure message with specific failure reasons and parameters to the network side. The network side recalculates the authentication quintuple after receiving the authentication failure message of the first authentication, and then initiates a secondauthentication request through the same domain. A serial processing mode is adopted for the authentication requests of the PS domain and the CS domain, so that the authentication success rate of themobile terminal to the network side is greatly improved.
