摘要： The present disclosure provides technical solutions for improving facial image capturing, recognition, and authentication, including: collecting a face image in response to a facial scan instruction (e.g., for facial recognition) using a camera of a mobile terminal; calculating a measure of image brightness (e.g., a luminance value) of the collected face image; enhancing, when a value of the measure of image brightness of the collected face image is less than a first preset threshold, luminance of light that is emitted from a display of the mobile terminal to a target luminance value, and re-collecting a face image using the camera of the mobile terminal and calculating a corresponding value of the measure of image brightness for the re-collected face image; and performing, when the value of the measure of image brightness of the re-collected face image falls within a preset value range, facial recognition based on the re-collected face image.

摘要： A method and an apparatus for generating a security token carrier, which belong to the field of data security, are disclosed. The method may include: generating multiple pieces of token information, establishing a relation which associates the token information with location information of a pre-set interactive security token carrier; obtaining security data which is set by a user for protecting the interactive security token carrier; and generating the interactive security token carrier by using the token information, the relation, the security data and public information of the interactive security token carrier. The apparatus may include: a token information processing module, a security data obtaining module and an interactive security token carrier generating module.
