Title: | Color image encryption based on interference and virtual optics | Authors: | Quan, Chenggen Tay, Cho Jui Fu, Yu Chen, Wen |
Keywords: | DRNTU::Science::Physics::Optics and light | Issue Date: | 2009 | Source: | Tay, C. J., Quan, C., Chen, W., & Fu, Y. (2009). Color image encryption based on interference and virtual optics. Optics and Laser Technology, (42), 409-415. | Series/Report no.: | Optics and Laser Technology | Abstract: | We propose two approaches to encrypt color images based on interference and virtual optics. In the first method, a color image is first decomposed into three independent channels, i.e., red, green and blue.Each channel of the input image is encrypted into two random phase-only masks based on interference.In the second method, a color image is first converted into an image matrix and a color map, and only the image matrix is encrypted into random-phase masks based on interference. After the phase masks are retrieved, a concept based on virtual optics is further applied to enhance the security level. Numerical simulations are demonstrated to show the feasibility and effectiveness of the proposed methods. | URI: | https://hdl.handle.net/10356/92123 http://hdl.handle.net/10220/6489 |
