Abstract: A trusted Java virtual machine provides a method for supporting tamper-resistant applications, ensuring the integrity of an application and its secrets such as keys. The trusted Java virtual machine verifies the integrity of the Java application, prevents debugging of the Java application, and allows the Java application to securely store and retrieve secrets. The trusted Java virtual machine environment comprises a TrustedDictionary, a TrustedBundle, an optional encryption method for encrypting and decrypting byte codes, and an underlying trusted Java virtual machine. The encrypted TrustedDictionary protects data while the TrustedBundle protects programming code, allowing applications to store secret data and secure counters. The application designer can restrict TrustedBundle access to only those interfaces that the application designer explicitly exports. The open source code may optionally be encrypted. Secrets required by the open source programming code of the application are encrypted in TrustedDictionary.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that processing of optimal encoding for digital contents takes too much time durations. SOLUTION: Genre of digital contents is acquired. According to the genre, optimal compression algorithm and optimal compression label are selected and decided automatically based on a table defined beforehand. Furthermore, encoding parameters which establish dynamic arbitration of contents, equalization level etc. are created automatically. The compression algorithm contains algorithms such as MPEG, AC3 and ATRAC. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: Software manufacturers examine their module and determine a range of addresses in memory which the module occupies. A protected range of addresses in memory is predefined to not allow changes, such as patching by hackers. Each manufacturer delivers the range of addresses describing the protected area and a known good version of their module to other manufacturers that they want to interoperate with. The other manufacturers return digital signatures on the protected area, and these digital signatures are stored in the first manufacturer's module. Correspondingly, the other manufacturers do the same with their own modules. Then, in order to effect a secure communication channel between two modules the modules first pass each other the signatures previously produced. Then, to ensure that communication is being effected with an authentic authorized module, through the use of the signature and the address ranges in the protected area, each module checks that the other module has not been patched. They each further verify that all the entry points in the other module they intend to call are in fact within the protected area. In the event that both modules are verified as being trustworthy, the modules now call each other freely. However, each module, when it is called must verify that it was called from within the protected area of the other module.

Abstract translation: 软件制造商检查其模块并确定模块占用的内存中的一系列地址。 内存中保护的地址范围被预先定义为不允许更改，例如黑客修补。 每个制造商提供描述保护区域的一系列地址和其模块的已知良好版本，以供他们想要互操作的其他制造商。 其他制造商在保护区域返回数字签名，这些数字签名存储在第一个制造商的模块中。 相应地，其他制造商也用自己的模块做同样的事情。 然后，为了实现两个模块之间的安全通信信道，模块首先通过彼此之前产生的签名。 然后，为了确保通过真实的授权模块进行通信，通过使用保护区域中的签名和地址范围，每个模块检查另一个模块未被修补。 他们每个进一步验证他们打算打电话的其他模块中的所有入口点实际上在保护区内。 如果两个模块都被验证为可靠的，那么这些模块现在可以自由地相互呼叫。 然而，每个模块在被调用时都必须验证它是否在另一个模块的保护区内被调用。

Abstract: A system for tracking usage of digital content on user devices. Electronic stores coupled to a network sell licenses to play digital content data to users. Content players, which receive from the network the licensed content data, are used to play the licensed content data. Additionally, a logging site that is coupled to thte network tracks the playing of the content data. In particular, the logging site receives play information from the network, and the play information includes the number of times that the content data has been played by the associated content player. Also provided is a method for tracking usage of digital content on user devices. According to the method, a license to play digital content data is sold to a user, and the licensed content data is transmitted to a content player for the user.; Further, information is transmitted to a logging site whenever the content data is played by the content player or copied from the content player to an external medium so that usage of the licensed content data can be tracked.
