The New York State Department of Financial Services announced that it has achieved two goals that have eluded the FBI for years ‒ mandatory retention of electronic communications and key escrow encryption.  The NYSDFS reached agreements with four bank ‒ Goldman Sachs, Deutsche Bank, Credit Suisse, and Bank of New York Mellon ‒ whereby the banks agreed to measures that will ensure law enforcement’s ability to access messages on the banks’ new Symphony Communications chat and messaging platform.  Under the deal, Symphony will retain for seven years copies of all electronic communications sent through its platforms, and the banks will store copies of the decryption keys for their messages with independent custodians.
