Abstract:This work presents a privacy-preserving communication architecture for Google and Apple map-based business discovery, local search, marketplaces, and AI-native telecommunications. The central problem is simple: once a user contacts or previews a business, conventional phone numbers, masked numbers, relay addresses, messaging handles, marketplace threads, or similar references may continue to provide a practical path for repeated callbacks, follow-up messages, spam, cross-query reuse, or post-inquiry harassment. The proposed architecture changes that model. A communication handle is treated as a routing reference, not as reusable communication authority. Possession, observation, copying, storage, forwarding, prior use, or leakage of the handle does not itself permit future contact. Each communication attempt remains non-effective until a protected enforcement point verifies bounded authority for the actual query, business identity, purpose, channel, permitted effect, freshness, quota, revocation state, and other applicable context. Only after successful validation may the corresponding communication-bearing resource—such as a call bridge, SIP/RTP path, WebRTC session, messaging thread, callback route, email relay, or notification path—become effective. The architecture also separates temporary preview communication from continuing contact authority. A business may be allowed to interact with a user during a limited preview window without thereby acquiring permanent reachability. Continued communication requires separately bounded and independently verifiable authorization. The broader objective is to move anti-spam and anti-harassment control from post-event blocking and moderation to pre-effectuation communication control: the handle may be visible, but reachability exists only when valid authority for that specific communication consequence is verified.
