An anonymous reader quotes a report from Bloomberg: Chinese billionaire Jack Ma proposed that the nation's top security bureau use big data to prevent crime, endorsing the country's nascent effort to build unparalleled online surveillance of its billion-plus people. China's data capabilities are virtually unrivaled among its global peers, and policing cannot happen without the ability to analyze information on its citizens, the co-founder of Alibaba Group Holding Ltd. said in a speech published Saturday by the agency that polices crime and runs the courts. Ma's stance resonates with that of China's ruling body, which is establishing a system to collect and parse information on citizens in a country where minimal safeguards exist for privacy. "Bad guys in a movie are identifiable at first glance, but how can the ones in real life be found?" Ma said in his speech, which was posted on the official WeChat account of the Commission for Political and Legal Affairs. "In the age of big data, we need to remember that our legal and security system with millions of members will also face change." In his speech, Ma stuck mainly to the issue of crime prevention. In Alibaba's hometown of Hangzhou alone, the number of surveillance cameras may already surpass that of New York's, Ma said. Humans can't handle the sheer amount of data amassed, which is where artificial intelligence comes in, he added. "The future legal and security system cannot be separated from the internet and big data," Ma said. Ma's speech also highlights the delicate relationship between Chinese web companies and the government. The ruling party has designated internet industry leaders as key targets for outreach, with President Xi Jinping saying in May last year that technology leaders should "demonstrate positive energy in purifying cyberspace."
