An authentication device may include a housing and a finger sensor carried by the housing and including first processing circuitry and a finger sensing area coupled thereto. The first processing circuitry may be configured to generate finger image data based upon a finger positioned adjacent the finger sensing area, and generate and store a first template based upon the finger image data. The authentication device may include second processing circuitry carried by the housing and configured to obtain the finger image data from the first processing circuitry. The second processing circuitry may be configured to generate a second template based upon the finger image data. The first processing circuitry may further be configured to obtain the second template from second processing circuitry, and validate the second template against the first template.

The invention discloses a two-dimensional code generation method and system and a document anti-counterfeiting method and system, and the method comprises the following steps: obtaining to-be-stored information, and obtaining a matched two-dimensional code template based on the to-be-stored information; generating first coded data corresponding to the two-dimensional code template based on the to-be-stored information, wherein the first coded data comprises a data code sequence and an error correction code sequence; performing interference processing on the error correction code sequence to obtain a corresponding interference sequence, and the interference sequence comprises a true error correction code and a false error correction code; and generating a corresponding two-dimensional codeon the two-dimensional code template based on the data code sequence and the interference sequence, wherein the two-dimensional code comprises a completely colored first pixel block and a partially colored second pixel block. According to the invention, by interfering the error correction code sequence and combining the design of the second pixel block, the generated two-dimensional code has certain vulnerability, pixels are easier to lose in the copying process, and unreadable copying is realized.
