The book tries to give students of computer science and professional
programmers a general understanding of operating systems--the programs
that enable people to share computers efficiently.
To make the sharing of a computer tolerable, an operating system must
enforce certain rules of behavior on all its users. One would therefore
expect the designers of operating systems to do their utmost to make them
as simple, efficient, and reliable as possible.
A number of operating systems made in the early 1960's had these
characteristics; but in the late 1960's designers were often overambitious
and built enormous systems with poor performance.
I see no inherent reason why operating systems should not reach the
quality of program construction found in present compilers; this will
require an understanding of the principles common to all operating systems
and a consistent use of safe methods of designing large programs. It is my
hope that this book will give you a start in this direction.
I assume that you are familiar with the basic structure of computers
and programming languages and have some experience in writing and
testing non-trivial programs. In a few cases a knowledge of elementary
calculus and probability theory is also needed.

基于全同态加密的安全人脸识别系统

指导老师：陈智罡(Zhigang Chen), 个人网站：
本项目获得第十二届全国大学生信息安全竞赛国家级二等奖。
特点说明：
随着人脸识别技术广泛使用，人脸数据安全问题的严重性也日益增长。
我们采用了全同态加密的方法来保证数据的安全性。
全同态加密：全同态加密支持加密域中密文的计算。那么全同态加密的提出就能够很好的解决计算隐私的问题。我们都知道人脸识别或者说机器学习甚至是整个人工智能，归根到底都是统计数学方法，那么就避不开计算，如此一来，我们就可以先用公钥将数据进行加密，加密后的密文进行数据传输和数值计算，计算结果还是为密文，用户收到密文结果后用私钥进行解密。这样就很好的保证了数据的隐私安全性。
项目难点：
1、Python和C++的跨平台开发，密码学的全同态加密算法采用C++语言编写，人工智能中的人脸识别算法采用Python编写；
2、
