MANILA -- The Commission on Elections on Thursday deposited at the central bank the last batch of source codes containing commands that will guide the May 13 election's automated system.

The 3 sets of codes were evaluated by local reviewers and US-based software testing company Pro V& to avoid "doubts" on integrity, said Comelec Executive Director and Project Management Office Head Jose Tolentino.

"None has said or found that there is any malicious code embedded in the source codes," he told reporters.

The source codes, saved in USB drives, were placed inside sealed envelopes. These were placed in a small cash box with a paper seal at a vault of the Bangko Sentral ng Pilipinas.

The poll automation law requires that source codes be deposited in escrow with the central bank.
