New software being trialled during the Olympics to predict where and when crime and social disorder may take place could be adopted by police in Scotland, England and Wales.
Details emerged on the anniversary of last summer's riots breaking out in London and follow recommendations for a central hub to analyse patterns such as heightened tension across social media sites.
The technology would make it easier for police to stop public disorder by picking up at an early stage should large groups of networkers be agitating over social tensions.
A report by Her Majesty's Chief Inspector of Constabulary in England and Wales, Sir Denis O'Connor, calls for an "all- source" information hub drawing together data from across social media.
Activity on sites such as Twitter, which has more than 175 million accounts worldwide, has already been used as a predictive tool, and earlier this year researchers at the University of California revealed how they had created a computer model that allows them to predict the stock market by scanning social networks.
Gordon Scobbie, deputy chief constable of Tayside Police and the lead officer for social media within the UK police, said: "In my national role in terms of social media and engagement we will be looking, post-Olympics, to develop this capability.
"We all need to understand the impact that social media has. We have no choice but to develop the anticipatory aspect to this."
Last week a British teenager was arrested on suspicion of "malicious communication" after sending abusive tweets to the UK's Olympic high diver, Tom Daley.
DCC Scobbie added: "There is a big issue around those people who are trolling and hiding behind fake or anonymous accounts.
"I can understand why this is necessary in countries where freedom of speech is restricted but in the UK I think if you've got something to say – as long as it's respectful – there is no need to be anonymous.
"We need to respect freedom of speech but equally we need to keep people safe from harm and online harassment and bullying is a big problem."
In November, The Herald revealed how senior police officers had held talks with Twitter, Facebook, Google and BlackBerry to see how information could best be shared for criminal investigations and how officers might be trained in social media.
Information sharing, which would be highly contentious among millions of social networkers around the globe, is likely to be opposed by the companies but officers will be trained in how to access the material available on sites such as Facebook.
A spokeswoman for the Metropolitan Police said: "The Metropolitan Police Service has procured the appropriate technology to monitor social media use in the police intelligence arena.
"This technology was introduced shortly after last year's summer disorder. It will continue to be used during and after the Olympics."
