    • Consumer networks, increasingly used for multimedia information and commercial content delivery, are destined to be heterogeneous. To provide QoS, it is necessary to adapt the multimedia stream to the heterogeneous network channel conditions and device capabilities. Meanwhile, security is an important component to restrict unauthorized multimedia content access and distribution. This suggests the need for new cryptography system implementations that can operate at different data rates, i.e., be scaled to various multimedia content, different network topology, changing bandwidth, and diverse receiver device capabilities. Content authentication is one important security tool for secure multimedia content communication. Conventional message authentication schemes do not offer suitable scalability for this new set of applications. The present invention addresses design of scalable media data stream authentication and presents a framework for multimedia authentication that supports various kinds of scalability.
    • 消费者网络越来越多地用于多媒体信息和商业内容传递,注定是异构的。 为了提供QoS,有必要使多媒体流适应异构网络信道条件和设备能力。 同时,安全是限制未经授权的多媒体内容访问和分发的重要组成部分。 这表明需要可以以不同的数据速率操作的新的密码系统实现,即,被缩放到各种多媒体内容,不同的网络拓扑,改变带宽以及各种接收机设备能力。 内容认证是安全多媒体内容通信的重要安全工具之一。 传统的消息认证方案不能为这一新的应用程序提供适当的可扩展性。 本发明解决了可扩展媒体数据流认证的设计,并提出了支持各种可扩展性的多媒体认证框架。

    • In some embodiments, systems and methods for visually rendering images rotate images at time of display based on annotations indicating needed rotations. In other embodiments, systems and methods for visually rendering images rotate images at time of display by determining a needed rotation for an image based on automatic orientation recognition. In further embodiments, systems and methods for visually rendering images rotate images at time of display by utilizing fuzzy logic to determine a best rotation angle for an image based on a none precise marking generated by computer vision or signal processing applied to the image. In yet further embodiments, systems and methods for annotating images annotate images at time of image capture, time of image display, or any time in between by using one or more of automatic image orientation recognition, user input specifying a needed rotation, and sensed orientation of an image capture mechanism.
