Mayor Walsh's office tells DigBoston that the city partnered with IBM to test software programs at both Boston Calling music festivals in 2013.
The paper says the city used surveillance cameras and facial recognition programs to record everyone who was near City Hall Plaza.
The software examined a person's height, clothing and skin color. It also reportedly monitored crowd movement, traffic patterns and searched for suspicious objects.
Boston police officials tell the paper that they were not part of the program and have not used the technology. However, DigBoston says it has pictures of officers monitoring the IBM cameras.
The city says it is still exploring options for how to use the software in the future.
