Authentication of information is arguably the most important security goal in modern electronic communication systems. Receiving a message on a computer terminal needs assurance that the message is coming from the claimed sender and it has not been tampered with. This assurance does not exist for most communications over the Internet today. Inadequate security for identification of users, devices and services, and authentication of messages has made attacks such as identity theft and fake websites, a major security concern. Authentication systems provide assurance for communicants about entities involved in the communication and the messages that are exchanged. Authentication systems must also meet the challenges resulting from the advancement of technologies and the introduction of new services. Applications such as social networking and instant tele-conferencing require secure authentication in dynamic groups. Multimedia data is produced at very large volumes and multimedia authentication systems have special requirements such as tolerance to small changes in data. A growing concern in authentication systems is users' privacy and the assurance that users' data cannot be later used to breach their privacy.

信息认证可以说是现代电子通信系统中最重要的安全目标。在计算机终端上接收消息需要确保消息来自声称的发送者并且没有被篡改。这种保证对于今天通过互联网进行的大多数通信来说并不存在。 用户、设备和服务的识别以及消息的认证的安全性不足，使得身份盗窃和虚假网站等攻击成为一个主要的安全问题。认证系统为通信者提供关于通信中所涉及的实体和所交换的消息的保证。认证系统还必须应对技术进步和新服务的推出所带来的挑战。社交网络和即时电话会议等应用需要在动态组中进行安全身份验证。 多媒体数据以非常大的量产生，并且多媒体认证系统具有特殊的要求，例如对数据中的小变化的容忍度。 认证系统中越来越多的关注是用户的隐私以及确保用户的数据以后不会被用来侵犯他们的隐私。
