Abstract
Provided herein are systems and methods for secure document sharing in a database system. For example, a system includes at least one hardware processor and a memory. The memory stores instructions that cause the at least one hardware processor to perform operations including receiving a query for a data set from a client device. The data set is shared in a data exchange by a data provider. The operations further include retrieving a data file responsive to the query for the data set. A security function is applied to the retrieved data file to generate a modified data file. A scoped uniform resource locator (URL) associated with the modified data file is encoded for transmission to the client device. The scoped URL includes an encrypted hash with a storage location of the modified data file.
