Privacy-preserving data linkage

Dynamic privacy preserving data linkage in distributed computing systems

US 12,626,006 B1, Amazon Technologies · with six co-inventors

A mapping authority issues transient, time-to-live-bound identifiers in place of durable ones, so services can link operational data to personal data without ever holding a persistent key to the person. Linkage expires by design, and personally identifiable information stays confined to a small privileged core.

Distributed state and stream processing

Preserving eventually consistent distributed state of multi-layer applications

US 12,093,751 B2, T-Mobile USA · sole inventor

Shared parameters between adjacent layers of a multi-layer application are held as conflict-free replicated data types and propagated through layer pointers, so distributed state converges without rebuilding the stack — over star, mesh, or hybrid topologies.

Distributed data stream programming and processing

US 11,412,058 B2, · US 11,706,312 B2, (continuation) T-Mobile USA · sole inventor

A single-program, multiple-data model for stream processing: code regions reference streams and processing nodes by rank, name, or range through global descriptors instead of hard-wired identifiers, so pipelines scale across a node pool without per-node code.

Eventually consistent data replication in queue-based messaging systems

US 11,063,780 B2, T-Mobile USA · sole inventor

Message state in geographically distributed queues is tracked with replicated data-type objects keyed by a unique message identifier and replicated asynchronously, so delivery converges across sites without synchronous coordination.

Secure transport and provisioning for constrained and non-IP devices

Secure and transparent transport of application level protocols to non-IP data delivery communication channels

US 11,516,263 B2, · US 11,909,781 B2, (continuation) T-Mobile USA · with P. Ramisetty and C. Asandului

A socket-wrapper layer presents IP and non-IP (NIDD) channels to DTLS as one ordinary UDP socket, so LwM2M devices reach the same server over either path with full security modes and no client changes — closing a gap in the cellular IoT standards.

Secure transport session resumption for constrained devices

US 11,824,841 B2, T-Mobile USA · sole inventor

Encrypted session state is parked on the server, so a constrained device waking from low-power sleep resumes its secure session without a full handshake — radio time and energy saved on every wake cycle.

Secure automated one time zero-touch bootstrapping and provisioning

US 11,533,616 B2, T-Mobile USA · sole inventor

Two-channel bootstrapping: a limited-use credential arrives out of band, unlocks a long-term credential over the data channel, and is overwritten by it — zero-touch provisioning with no pre-installed secret.

Cellular IoT platform mechanics

Smart event monitoring of IoT devices using message queue

US 11,836,548 B2, T-Mobile USA · with G. K. Manika and P. Ramisetty

Device notifications land in message queues configured per consumer preference, so each consumer receives only its subset of fleet events; monitoring scales with the queue, not with the fleet.

Duplex load balancing for massive IoT applications

US 11,425,043 B2, T-Mobile USA · sole inventor

A middlebox binds client address, server address, and an application client marker, so reverse translation still finds the client when NAT bindings expire or the application moves between servers — bidirectional load balancing for very large device populations.

Efficient interactions to support internet-of-things (IoT) device power saving mode

US 11,089,065 B2, T-Mobile USA · sole inventor

3GPP reachability notifications are translated into equivalent non-3GPP status messages that tell the application server to queue traffic while a device sleeps and release it on wake — power-saving mode made transparent to the application layer.

Media delivery and network hardware

Systems and methods related to establishing a temporary trust relationship between a network-based media service and a digital media renderer

EP 3117575 B1, (no longer in force) · CN 106105133 B, · US 11,178,131 B2, Ericsson · sole inventor · PCT/IB2014/059832

A network media service obtains a renderer's certificate and issues a temporary token, establishing a scoped, time-limited trust relationship with an untrusted device — the pattern behind cloud-delivered TV to home renderers.

Small form-factor pluggable module

EP 3298745 B1, · US 10,523,795 B2, Ericsson · with R. Brunner, R. J. Brunner, and S. Lessard · PCT/IB2015/053803

An SFP module that inspects packet payloads and rewrites headers in transit, adding packet-processing capability to legacy network equipment without replacing the hardware.
