Abstract: The present disclosure provides techniques to identify suspicious user logins. These techniques may include acquiring, by a computing device, a routing path associated with a user login based on login information. The computing device may extract current routing characteristic information from the routing path, and identify whether the current user login is suspicious based on the current routing characteristic information. These techniques reduce the influence of IP address changes on user identification as well as errors associated with user identification, and identify geographic positions more accurately.

Abstract: A proxy gateway anti-virus method, a pre-classifier, and a proxy gateway are provided. The method includes: receiving a resource obtaining request for obtaining a to-be-transmitted resource; sending a pre-detection request to a network element that stores the to-be-transmitted resource, to obtain attribute information of the to-be-transmitted resource; judging, based on an anti-virus policy and according to the attribute information, whether the to-be-transmitted resource needs anti-virus scanning; if judged yes, performing anti-virus scanning on the to-be-transmitted resource that is subsequently obtained; and if judged no, transparently transmitting the to-be-transmitted resource that is subsequently obtained.

Abstract: Identity authentication comprises: determining, in response to a request from a first device operated by a source user, that an identity authentication is to be performed for the source user; identifying a target user who is deemed to satisfy at least a preset condition, the target user being a user other than the source user; generating validation information to authenticate identity of the source user; sending the validation information to a second device operated by the target user; receiving a validation response from the first device operated by the source user; and performing identity authentication, including verifying whether the validation response received from the first device operated by the source user matches the validation information sent to the second device.

Abstract: A base station of a wireless system comprises a local clock source and timing circuitry coupled to the local clock source. The timing circuitry is configured to adjust at least one parameter of the local clock source based at least in part on timing information extracted from designated portions of each of one or more frames of a synchronous transport signal received in the base station. The base station may further comprise a physical layer device, such as a mapper, configured to extract the timing information from the designated portions of each of the one or more frames of the synchronous transport signal. The designated portions of the one or more frames of the synchronous transport signal from which the timing information is extracted may comprise designated overhead bytes of the one or more frames, such as, for example, transport overhead (TOH) bytes.

Abstract: Operation identification is obtained from a captured barcode. An authentication criterion is determined whether is satisfied. If the authentication criterion is met, the operation identification and stored account information is sent to server for authenticating based on the account information. The authentication criterion includes whether a similarity degree between an image characteristic of a first surrounding image of a barcode and an image characteristic of a second surrounding image of the barcode is larger than or equal to a present threshold. The second surrounding image is an authenticated surrounding image of the barcode such as a surrounding image when the barcode is generated. The present techniques ensure that a successful authentication is possibly returned only when the first surrounding image is in consistent with the second image. It is difficult for the barcode placed on a fake webpage or sent through group sending by a hacker to pass authentication.

Abstract: A method and an apparatus of identifying a proxy IP address. The method includes determining a first network delay between a server and a terminal that establishes a TCP connection with the server using an IP address as a user IP address; determining a second network delay between the server and a router that is a hop prior to the IP address; determining whether a ratio between the first network delay and the second network delay is greater than a threshold; and identifying the IP address as a proxy IP address when the ratio between the first network delay and the second network delay is greater than the threshold. Using the technical solution of the present disclosure, identifying whether an IP address is a proxy IP address can be made quickly and accurately.

Abstract: A human biological characteristic file corresponding to a particular identity is received and used as a base file. A characteristic code to be authenticated is obtained according to a human biological characteristic of a person who requests identity authentication when an identity authentication request corresponding to the particular identity is received. A base characteristic code is collected from a base file. A collecting algorithm applied for collecting the base characteristic code is the same as or matches an algorithm applied for obtaining the characteristic code. The present techniques determine whether the base characteristic code and the characteristic code correspond to a same human biological characteristic. If a result is positive, the identity authentication request is verified.

Abstract: The present disclosure introduces a method, a client, a server and a system of login verification. When a user logins, the client obtains a login request from the user for logging into an under-protected account system, where the login request includes at least an account to be logged in, determines property information of a current related account system corresponding to the account to be logged in from property information stored in a current login host, generates login verification information including at least the property information of the current related account system, and sends the login verification information to a server. The server verifies a login activity of the user based on the pre-stored reliable property information corresponding to the account to be logged in. Thus, the login verification process is simplified and the efficiency of login verification using the server is enhanced.

The controller circuitry in detecting a current message sequence is configurable in at least first and second different monitoring modes each associated with a different message format. The monitoring mode of the controller circuitry may be adaptively configured based at least in part on a detected message sequence.
