摘要:
Techniques are disclosed for performing operations in an authentication token or other cryptographic device in a system comprising an authentication server. In one aspect, a code generated by the authentication server is received in the cryptographic device. The code may have associated therewith information specifying at least one operation to be performed by the cryptographic device. The cryptographic device authenticates the code, and responsive to authentication of the code, performs the specified operation. If the code is not authenticated, the operation is not performed. The code may be determined as a function of a one-time password generated by the authentication server. The function may also take as an input an identifier of the operation to be performed.

摘要:
A technique of authenticating a person involves obtaining, during a current authentication session to authenticate the person, a first authentication factor from the person and a second authentication factor from the person, at least one of the first and second authentication factors being a biometric input. The technique further involves performing an authentication operation which cross references the first authentication factor with the second authentication factor. The technique further involves outputting, as a result of the authentication operation, an authentication result signal indicating whether the authentication operation has determined the person in the current authentication session likely to be legitimate or an imposter. Such authentication, which cross references authentication factors to leverage off of their interdependency, provides stronger authentication than conventional naïve authentication.

Authentication codes associated with an entity are generated. A stored secret associated with an entity is retrieved. At a first point in time, a first dynamic value associated with a first time interval is determined. A first authentication code based on the first dynamic value is determined. At a second point in time, a second dynamic value associated with a second time interval is determined. A second authentication code based on the second dynamic value is determined. The first and second authentication codes are derived from the stored secret and the amount of time between the first and second points in time is different from the length of the first time interval.

A technique performs an authentication operation using pulse and facial data from a user. The technique involves obtaining current pulse data from a user, and performing a comparison between the current pulse data from the user and expected pulse data for the user. The technique further involves generating an authentication result based on the comparison between the current pulse data and the expected pulse data. The authentication result may control user access to a computerized resource. Since such a technique uses pulse data, a perpetrator cannot simply submit a static image of a subject's face to circumvent the authentication process. In some arrangements, the technique involves obtaining videos of human faces and deriving cardiac pulse rates from the videos. For such arrangements, a standard webcam can be used to capture the videos. Moreover, such techniques are capable of factoring in circadian rhythms and/or aging adjustments to detect and thwart video replay attacks.

An improved technique for assessing the security status of a device on which a soft token is run collects device posture information from the device running the soft token and initiates transmission of the device posture information to a server to be used in assessing whether the device has been subjected to malicious activity. The device posture information may relate to the software status, hardware status, and/or environmental context of the device. In some examples, the device posture information is transmitted to the server directly. In other examples, the device posture information is transmitted to the server via auxiliary bits embedded in passcodes displayed to the user, which the user may read and transfer to the server as part of authentication requests. The server may apply the device posture information in a number of areas, including, for example, authentication management, risk assessment, and/or security analytics.

A method, system, and apparatus for agile generation of one time passcodes (OTPs) in a security environment, the security environment having a token generator comprising a token generator algorithm and a validator, the method comprising generating a OTP at the token generator according to a variance technique; wherein the variance technique is selected from a set of variance techniques, receiving the OTP at a validator, determining, at the validator, the variance technique used by the token generator to generate the OTP, and determining whether to validate the OTP based on the OTP and variance technique.
摘要:
A single sign-on technique allows multiple accesses to one or more applications or other resources using a proof-of-authentication module operating in conjunction with a standard authentication component. The application or other resource issues an authentication information request to the standard authentication component responsive to an access request from the user. The application or other resource receives, responsive to the authentication information request, a proof-of-authentication value from the standard authentication component, and authenticates the user based on the proof-of-authentication value. The standard authentication component interacts with the proof-of-authentication module to obtain the proof-of-authentication value. The proof-of-authentication module is configured to generate multiple proof-of-authentication values for authentication of respective access requests of the user.

A method, electronic apparatus and computer program product for performing authentication operation is disclosed. An authentication request is received from user of computerized resource. The request comprises user identifier identifying user. The authenticity of user is verified based on user identifier. An access session is established in which user can access resource in response to successfully verifying user. An electronic input signal is received from electronic input device during session. The device is configured to take a biometric measurement from the user. Biometric data is derived from signal. A comparison is performed between biometric data and expected biometric data. An authentication result is generated based on comparison between biometric data and expected biometric data, wherein result can be used for further authentication of user during session.
