    • Provided are apparatus, system and methods for accessing information utilizing an authentication system for verifying that a user is an authorized user of the information access device, and that activation of the device is valid to access the information. The authentication system included in the device issued to an authorized user, reads a user's fingerprint using a reader and compares the user's fingerprint as read with a stored fingerprint of the authorized user of the device, thereby determining if the user is the authorized user. If the user is the authorized user, a pseudo-random generator generates a personal identification number for use by the user to validate activation of the device for accessing information.
    • 提供了使用认证系统访问信息的装置,系统和方法,用于验证用户是信息访问设备的授权用户,并且设备的激活对于访问信息是有效的。 包含在发给授权用户的设备中的认证系统使用读取器读取用户的指纹,并将用户的指纹读取与设备的授权用户的存储指纹进行比较,从而确定用户是否是授权用户。 如果用户是授权用户,则伪随机生成器生成个人识别号码,供用户使用以验证用于访问信息的设备的激活。

    • A method and computer device for generating a pseudo-random value string of N characters for an authentication token. The method partitions a message digest into at least one segment, each segment comprising a number of consecutive bits from the message digest, wherein the segments are consecutive when taken together, such that a first segment begins with the most significant bit and a last segment ends with the least significant bit. For each segment, the method converts the bits to a decimal value, and compares the decimal value to a set of satisfactory values, wherein each entry in the set includes a valid decimal value and a corresponding character representation. When the decimal value matches a valid decimal value in set of satisfactory values and the length of the pseudo-random value is less than N, the method appends the corresponding character representation of the decimal value to the pseudo- random value.
    • 一种用于生成用于认证令牌的N个字符的伪随机值字符串串的方法和计算机设备。 该方法将消息摘要分割成至少一个段,每个段包括来自消息摘要的多个连续位,其中,段合在一起时是连续的,使得第一段以最高有效位开始,最后一段结束 具有最低有效位。 对于每个段,该方法将位转换为十进制值,并将十进制值与一组令人满意的值进行比较,其中集合中的每个条目包括有效的十进制值和相应的字符表示。 当十进制值与满意值的集合中的有效十进制值匹配,并且伪随机值的长度小于N时,该方法将十进制值的相应字符表示附加到伪随机值。

    • An authentication token that comprises a flexible solar cell array, a display, a processor, and a memory disposed in communication with the processor. Wherein the processor is configured to receive a signal from the flexible solar cell array, and, if the authentication token has been activated, compute a one-time passcode, and send the one-time passcode to the display. A device for communicating with the authentication token comprises a slot for receiving the authentication token; an optical character reader for recognizing characters on the display of the authentication token, and a hi-intensity strobe light for sending light pulses to the flexible solar cell array.
    • 包括柔性太阳能电池阵列,显示器,处理器和与处理器通信的存储器的认证令牌。 其中处理器被配置为从柔性太阳能电池阵列接收信号,并且如果认证令牌被激活,则计算一次性密码,并将一次性密码发送到显示器。 用于与认证令牌进行通信的设备包括用于接收认证令牌的时隙; 用于识别认证令牌的显示上的字符的光学字符读取器,以及用于向柔性太阳能电池阵列发送光脉冲的高强度闪光灯。
