Each flaw will score at least $1,000 under the program announced on Thursday to back up automated checks that have failed to block malware and other problems that security experts say infect the 8-year-old app store far more than Apple Inc's rival App Store.

Google will partner with HackerOne, a bug bounty program management website, to target a list of apps and flaws such as those that allow a hacker to redirect a user to a phishing website or infect a gadget with a virus.

Software scans cannot match a person's ability to discover "a truly creative hack," Vineet Buch, director of product management for Google Play Apps and Games, said in an interview.

The Google Play Security Reward Program effectively sponsors research into software created by other companies. Bug bounties by Microsoft Corp, Apple and Alphabet have been awarded only for tracing flaws in their own software.

"We don't just care about our own apps, but rather the overall health of the ecosystem," Buch said. "It's like offering a reward for a missing person even if you don't know who the missing person is personally."

Google did not reveal the funding for its program, but said it would start small.

Google's bug bounty program for its Android mobile operating system, launched in June 2015, doled out $1.5 million for hundreds of vulnerability reports over its first two years.
