Image Encryption and Decryption Method Combined with Physiological Features and Image Capture Device

Abstract

The present invention provides an image encryption and decryption method combined with physiological characteristics and its image capture device. The image encryption and decryption method executes an encryption program and a decryption program. The encryption program includes: using the image capture module to capture a plurality of first iris images respectively. The encryption and decryption module is used to generate the first key according to the plurality of first iris images. When the image capture module generates a photo, the control encryption and decryption module uses the first key to encrypt the photo to generate an encrypted photo. The decryption program includes: controlling the encryption and decryption module to use the first key to decrypt the encrypted photo to restore the photo.

Description

technical field [0001] The present invention relates to an image encryption and decryption method, in particular to an image encryption and decryption method capable of combining physiological features, and an image capture device using the method. Background technique [0002] At present, most of the camera lenses of consumer cameras have more than 10 million pixels, and many high-end mobile phones even have camera lenses with more than 20 million pixels. Coupled with the portability of consumer cameras and mobile phones, people are getting used to using cameras or Mobile phones record all kinds of information in life and work. At the same time, the possibility of storing highly private data in cameras or mobile phones is also increasing. [0003] Therefore, the problem of leakage of user privacy due to leakage of photos from cameras or mobile phones has become more and more serious. When a camera or mobile phone is lost, its owner is often worried about the risk of leakin...

Problems solved by technology

[0004] Although it is currently useful to set a password to access the photos on the camera or mobile phone, this method cannot prevent those who want to access the photos in the camera or mobile phone by stealing the password. Another way It is a setting that can use the application program to encrypt photos. However, once the mobile phone or camera falls into the hands of someone who is familiar with the way the user operates the application program, there is still the possibility of leakage of private data
