Aspects of the disclosure relate to preventing unauthorized access to information resources by deploying and utilizing multi-path data relay systems and sectional transmission techniques. A computing platform may receive, from one or more data storage computer systems, source data associated with a source dataset. Subsequently, the computing platform may generate at least two data blocks based on the source data received from the one or more data storage computer systems, and the at least two data blocks may include one or more overlapping portions. Thereafter, the computing platform may apply one or more tags to the at least two data blocks, thereby producing at least two tagged data blocks. Then, the computing platform may select at least two paths for transmitting the at least two tagged data blocks. Subsequently, the computing platform may send, across the at least two selected paths, the at least two tagged data blocks.
