P3: toward privacy-preserving photo sharing

Abstract: With increasing use of mobile devices, photo sharing services are experiencing greater popularity. Aside from providing storage, photo sharing services enable bandwidth-efficient downloads to mobile devices by performing server-side image transformations (resizing, cropping). On the flip side, photo sharing services have raised privacy concerns such as leakage of photos to unauthorized viewers and the use of algorithmic recognition technologies by providers. To address these concerns, we propose a privacy-preserving photo encoding algorithm that extracts and encrypts a small, but significant, component of the photo, while preserving the remainder in a public, standards-compatible, part. These two components can be separately stored. This technique significantly reduces the accuracy of automated detection and recognition on the public part, while preserving the ability of the provider to perform server-side transformations to conserve download bandwidth usage. Our prototype privacy-preserving photo sharing system, P3, works with Facebook, and can be extended to other services as well. P3 requires no changes to existing services or mobile application software, and adds minimal photo storage overhead.

A flexible transaction model for software engineering

Abstract: It is generally recognized that the classical transaction model, providing atomicity and serializability, is too strong for certain application areas since it unnecessarily restricts concurrency. The author is concerned with supporting cooperative work in multiuser design environments, particularly teams of programmers cooperating to develop and maintain software systems. An extended transaction model that meets the special requirements of software engineering projects is presented, possible implementation techniques are described, and a number of issues regarding the incorporation of such a model into multiuser software development environments are discussed. >

Protocol architecture for universal personal computing

Abstract: This paper presents a new paradigm for network computing over the Internet called universal personal computing, where mobile users can access computing resources, network services, and personalized computing environments anywhere using any available terminals The user and system requirements are defined, and an agent-based protocol architecture required to manage different mobile objects, ie, users and terminals, in this computing environment is presented Modifications of connection setup procedures between user application programs to enable addressing based on a global user identity are considered The use of personal agents to facilitate interworking and management functions is proposed

A high-performanance remote computing platform

Abstract: The pervasive computing environment and the wide network bandwidth provide users more opportunities to utilize remote computing resources. In this paper, we introduce a high-performance remote computing platform to enable thin clients to access the applications in remote servers. Our system employs a compression-friendly model, where all the data redundancies are exploited in the compression viewport. Within this model, we also propose a unified coding scheme to efficiently compress the vast-spectral screens. Several mechanisms are further proposed to improve interactivity and reduce the bandwidth consumption in the system, including adaptive transmission for heterogeneous display devices. Simulations with real applications demonstrate that our system significantly outperforms previous thin-client systems. Especially for video playback under moderate- and low-bandwidth network conditions, our system can achieve the frame update rate 5 times as high as the previous counterparts.

CompuP2P: An Architecture for Internet Computing Using Peer-to-Peer Networks

Abstract: Internet computing is emerging as an important new distributed computing paradigm in which resource intensive computing is integrated over Internet-scale networks. Over these large networks, different users and organizations share their computing resources, and computations take place in a distributed fashion. In such an environment, a framework is needed in which the resource providers are given incentives to share their resources. CompuP2P is a lightweight architecture for enabling Internet computing. It uses peer-to-peer networks for sharing of computing resources. CompuP2P create dynamic markets of network accessible computing resources, such as processing power, memory storage, disk space, etc., in a completely distributed, scalable, and fault-tolerant manner. This paper discusses the system architecture, functionality, and applications of the proposed CompuP2P architecture. We have implemented a Java-based prototype, and our results show that the system is light-weight and can provide almost a perfect speedup for applications that contain several independent compute-intensive tasks
