Abstract: Methods, apparatus and articles of manufacture for authenticating by labeling are provided herein. A method includes identifying each of one or more graphical-based input elements to be associated with a computing device in response to user activity in connection with the computing device; identifying each of one or more graphical-based labels to be assigned to the one or more graphical-based input elements; displaying (i) the one or more graphical-based input elements and (ii) the one or more graphical-based labels via an interface of the computing device; generating a prompt via the computing device interface; and processing input cryptographic information entered via the computing device interface in response to the prompt against (i) the one or more graphical-based input elements and (ii) the one or more graphical-based labels.

Abstract: Methods, apparatus and articles of manufacture for authenticating by labeling are provided herein. A method includes establishing a set of cryptographic information, wherein said set of cryptographic information comprises (i) a set of one or more graphical-based input elements and (ii) one or more graphical-based labels assigned to the set of one or more input elements in accordance with a given arrangement; generating a prompt via a computing device interface in connection with an authentication request to access a protected resource associated with the computing device; processing input cryptographic information entered via the computing device interface in response to the prompt against the set of cryptographic information; and resolving the authentication request based on said processing.

Abstract: A method is used in managing use of security keys. Based on a request for use of a key that serves as part of a data security system, a set of criteria to apply to the request is determined. The set of criteria pertain to security management of the key that is subject of the request. The set of criteria is applied to the request; and a result is determined based on the application of the set of criteria.

Abstract: There is disclosed a method for use in authenticating a user. The method comprises obtaining a biometric input comprising a plurality of biometric attributes distinct to a user. Additionally, the method comprises selecting at least one biometric attribute in the obtained biometric input as a currently active biometric attribute. Furthermore, the method comprises based on the at least one selected currently active biometric attribute, creating a currently active biometric profile for the user for facilitating the authentication of the user.

Abstract: Encryption key(s) and/or other protected material are protected on devices. A secret splitting scheme is applied to a secret, S, that protects at least one data item to obtain a plurality of secret shares. At least one secret share is encrypted to provide at least one encrypted secret share using an encryption scheme that uses at least one other secret share as the encryption key. A subset of the plurality of secret shares and encrypted secret share(s) is required to reconstruct the secret, S. One or more secret shares and/or encrypted secret shares are provided to at least one device, for example, based on a corresponding key-release policy, to allow access to the data item(s) secured by the secret, S. The secret, S, comprises, for example, a secret key used to protect at least one content item and/or a key used to protect one or more of a content container and a vault storing one or more protected data items.

Abstract: There is disclosed a method for use in authenticating a user. The method comprises obtaining, by an electronic apparatus, a biometric input from a user comprising a plurality of biometric attributes distinct to the user, wherein the biometric attributes comprise at least one currently active and at least one currently inactive biometric attribute for authentication at an authentication server. Additionally, the method comprises selecting, by the electronic apparatus, the at least one currently active biometric attribute for authenticating the user. Furthermore, the method comprises outputting, by the electronic apparatus, an authentication output including at least one biometric factor based on the at least one selected currently active biometric attribute, wherein the authentication output acts as an authentication input to a user authentication operation performed by the authentication server.

Abstract: Techniques for secure voice authentication. In one example, a method includes the following steps. A first computing device initiates establishment of a secure channel between the first computing device and a second computing device. The first computing device includes a trusted device and the second computing device at least partially hosts a service that a user of the trusted device seeks to access. A prompt is received at the first computing device from the second computing device over the secure channel. The prompt requests a user voice response for use in making an authentication decision for the user based on the user voice response.

Abstract: Access of a user to a protected resource during a session is controlled by issuing an authentication information request and receiving authentication information from the user responsive to the authentication information request. The user is authenticated based upon verification of the received authentication information. One or more of the issuing, receiving and authenticating steps are repeated during the session to re-authenticate the user. At least a portion of the authentication information that is used during the re-authentication is different from a corresponding portion of the authentication information that was used during the initial authentication. A secure channel is optionally established between the user and the protected resource responsive to the initial verification. The secure channel can optionally be re-established with the re-authentication using the different portion of the authentication information.

Abstract: A method and system for use in indicating errors in connection with devices, wherein at least one of the devices comprises a display is disclosed. An error indicator suitable for indicating an error in connection with the device is stored. The error indicator is mapped to a potential error in connection with the device. An error is detected in connection with the device. The error in connection with the device is determined in response to detecting the error. Based on determining the error, the error indicator is displayed on the display for enabling determination of the error in connection with the device.

Abstract: A technique provides security to an electronic device. The technique involves disposing a microprocessor between a printed circuit board and a circuit element to restrict physical access to the microprocessor, the microprocessor having (i) a bottom which faces the printed circuit board in a first direction and (ii) a top which faces the circuit element in a second direction which is opposite the first direction. The technique further involves delivering power to the microprocessor from a power source while the microprocessor is disposed between the printed circuit board and the circuit element, the microprocessor performing electronic operations in response to the power delivered from the power source. The technique further involves electronically altering or preventing the microprocessor from further performing the electronic operations in response to tampering activity on the circuit element. Such detection of the tampering activity may involve monitoring a covert signal for tamper evidence detection.
