Abstract
Disclosed are devices, systems, and methods for securing data using attribute based data access. The data may correspond to a sensory environment, and the data is secured at the device. The device secures the data by segmenting the data into number of segments and defining an access policy, further submitting the access policy to a PKG of system for generating Access Tree having attributes at different level for accessing the data. These Access Trees are securely stored on the device using IBE mechanism. Further, the data after being secured, is uploaded to a system for analysis. At the system, an access request may be received for accessing the data. The access request further includes a request attribute, whereby the system verifies if the attribute satisfies the Access Policy. If the verification is positive, an access may be provided to the data accessor for accessing the data.
