Abstract
Strict security is ensured with respect to information in originals scanned by an MFP. There are provided: password detector for judging if original information obtained by decoding the two-dimensional code of original images contains a one-way hash value generated from a password; password input for prompting input of a password in the case where it is determined by the password detector that a hash value is contained in the original information; password verifier for using the one-way hash value to verify a password input by the password input; and converter for converting the original images into an electronic file protected by the password input by the password input.
Claims9
An image processing apparatus, comprising:
- password detecting means for judging whether original information obtained by decoding a two-dimensional code in an original image contains a one-way hash value generated from a password;
- password inputting means for prompting input of a password in the case where it is determined by said password detecting means that a hash value is contained in the original information;
- password verifying means for using the one-way hash value to verify a password input by said password inputting means;
- and
- convening means for convening the original image into an electronic file protected by the password input by said password inputting means.
An image processing method executed by an image processing apparatus, comprising the steps of:
- detecting a password by determining whether original information obtained by decoding a two-dimensional code in an original image contains a one-way hash value generated from a password;
- inputting a password by prompting input of a password in the case where it is determined in said password detecting step that a hash value is contained in the original information;
- verifying a password by using the one-way hash value to verify the password input in said password inputting step;
- and
- convening the original image into an electronic file protected by the password input in said password inputting step.
A program on a computer-readable medium causing an image processing apparatus to execute an image processing method, the image processing method comprising the steps of:
- detecting a password by determining whether original information obtained by decoding a two-dimensional code in an original image contains a one-way hash value generated from a password;
- inputting a password by prompting input of a password in the case where it is determined in the password detecting step that a hash value is contained in the original information;
- verifying a password by using the one-way hash value to verify the password input in the password inputting step;
- and
- convening the original image into an electronic file protected by the password input in the password inputting step.
