Provenance Description of Metadata Vocabularies for the Long-term Maintenance of Metadata

1 Introduction Maintaining the accessibility of collections for future generations is a central mission of libraries and other memory institutions. Metadata longevity should be ensured to keep the long-term accessibility of data collections. However, we are facing the difficulties in metadata longevity, such as the consistent maintenance of metadata, maintenance of metadata vocabularies and metadata terms, structural and syntactic features of metadata, metadata description rules, and so forth. This paper focuses on consistent maintenance of metadata

Phonion: Practical Protection of Metadata in Telephony Networks


The majority of people across the globe rely on telephony networks as their primary means of communication. As such, many of the most sensitive personal, corporate and government related communications pass through these systems every day. Unsurprisingly, such connections are subject to a wide range of attacks. Of increasing concern is the use of metadata contained in Call Detail Records (CDRs), which contain source, destination, start time and duration of a call. This information is potentially dangerous as the very act of two parties communicating can reveal significant details about their relationship and put them in the focus of targeted observation or surveillance, which is highly critical especially for journalists and activists. To address this problem, we develop the Phonion architecture to frustrate such attacks by separating call setup functions from call delivery. Specifically, Phonion allows users to preemptively establish call circuits across multiple providers and technologies before dialing into the circuit and does not require constant Internet connectivity. Since no single carrier can determine the ultimate destination of the call, it provides unlinkability for its users and helps them to avoid passive surveillance. We define and discuss a range of adversary classes and analyze why current obfuscation technologies fail to protect users against such metadata attacks. In our extensive evaluation we further analyze advanced anonymity technologies (e.g., VoIP over Tor), which do not preserve our functional requirements for high voice quality in the absence of constant broadband Internet connectivity and compatibility with landline and feature phones. Phonion is the first practical system to provide guarantees of unlinkable communication against a range of practical adversaries in telephony systems.

Supporting Book Search: A Comprehensive Comparison of Tags vs. Controlled Vocabulary Metadata

search applications such as book seller or library catalogs. Even Amazon relies on information about the book (metadata) more than the book content and complements its search functionality with additional features, such as a recommendation system based on purchase histories. This article explores the effectiveness of different book metadata elements in satisfying book search requests This text is an adapted and extended version of two conference papers: [ 5 ] and [ 6 ]. .
