TLDR
This paper proposes a mechanism that creates a verification object (VO) for checking the integrity of each query result produced by an edge server - that values in the result tuples are not tampered with. Expand

Authenticating the query results of text search engines
TLDR
We formulate the properties that define a correct result, map the task of processing a text search query to adaptations of existing threshold-based algorithms, and devise an authentication scheme for checking the validity of a result. Expand

Scalable Verification for Outsourced Dynamic Databases
TLDR
We introduce a protocol, built upon signature aggregation, for checking the authenticity, completeness and freshness of query answers. Expand

StegFS: a steganographic file system
TLDR
We introduce StegFS, a steganographic file system that securely hides user-selected files in a file system so that, without the corresponding access keys, an attacker would not be able to deduce their existence. Expand

Load Sharing in Distributed Multimedia-on-Demand Systems
TLDR
The authors explore the feasibility of linking up several small multimedia servers to a (limited-capacity) network and allowing servers with idle retrieval bandwidth to help out servers that are temporarily overloaded; the goal is to minimize the waiting time for service to begin. Expand

Authenticating Multi-dimensional Query Results in Data Publishing
TLDR
This paper introduces a mechanism for users to verify that their query answers on a multi-dimensional dataset are correct, in the sense of being complete (i.e., no qualifying data points are omitted) and authentic. Expand

Partially materialized digest scheme: an efficient verification method for outsourced databases
TLDR
We propose a result verification approach for one-dimensional queries, called Partially Materialized Digest scheme (PMD), that applies to both static and dynamic databases. Expand

Multiclass Query Scheduling in Real-Time Database Systems
TLDR
We introduce and evaluate a new algorithm called Priority Adaptation Query Resource Scheduling (PAQRS) for handling both single class and multiclass query workloads. Expand

Transition scheduling in (multiclass real-time database systems
TLDR
A dynamic priority assignment scheme that improves the chances for long transactions to meet their time constraints, thereby providing a fairer mechanism for use in multiclass RTDBS transaction scheduling. Expand
