Sentence examples for data location verification from inspiring English sources

Fig. 1 Data location verification approach classes.

Such a dedicated hardware can be remotely accessed by users when data location verification in required.

Data location verification is required due to legal, privacy, and performance constraints.

A review and a classification of landmark-based data location verification approaches in the cloud are proposed.

This paper presents a survey of the most referenced landmark-based data location verification approaches, which are flexible, low cost, and not restrictive for CSPs, as they do not require installation of dedicate software of hardware in CSPs.

Fig. 1 Data location verification approach classes In case users do not trust CSP, Cloud Framework-based approaches can be combined with some hardware root of trust, administered by a third party, to ensure the framework is really run on the CSP.

In caching data attack, CSP stores most of the data at a remote location while storing in its local cache data needed by location verification process.

Such an attack is implemented differently depending on interactions between the verification process and the data access process: No interaction: location verification and data access processes are independent, i.e. the Verifier does not rely on data accesses to verify the location.

When a data access request is for location verification, CSP fetches data in its local cache, otherwise the request is forwarded to the remote node of data storage before sending a response to user.

In the latter, data used in the location verification are not relevant to the user so the proxy generates any data to answer the request, while in the caching attack data are used both by location verification process and by conventional user's applications.

Pre-verification landmark selection: after training step and when the user requests location verification, data collected by all trained landmarks and their distance models are considered.
