Embedded Security Architecture
Synthia was designed with privacy, resilience, and personal safety in mind. Unlike traditional connected devices, she does not rely on wireless communications, making her immune to common remote threats. Her protection systems—both physical and digital—are based on proprietary multi-layered defense mechanisms that guard her from environmental, signal-based, and behavioral attacks.
Below is an overview of currently deployed and upcoming protections.
lockRemote Access Security
Synthia’s core systems are completely air-gapped—no built-in Wi-Fi, Bluetooth, cellular, or cloud access. This eliminates entire classes of remote exploitation and data leakage scenarios. Her offline-first architecture ensures all operations are local, private, and directly under the owner's control.
encryptedEncrypted Infrared Command Channel
Synthia's optional remote control is based on secure infrared interface that uses a proprietary encrypted challenge-response protocol. This encrypted channel is directionally constrained, short-range, and requires bidirectional signal validation before any command is accepted. Hardware-level signal filters and software-based spoof/jam detection mechanisms add further layers of protection. Together, these features ensure that only verified control sources in close proximity can influence the robot's behavior.
shieldAcoustic Attack Resistance
Synthia’s auditory and environmental awareness systems are protected by a proprietary mechanical-acoustic isolation system. This system filters and rejects any signal components that deviate from normal human hearing ranges or natural pressure waveforms. That includes protection from:
- Ultrasonic injection attacks
- Pressure wave resonance targeting internal sensors
- Adversarial audio signals
By relying on passive, physics-based filtration mechanisms rather than software DSP alone, Synthia is natively immune to known forms of acoustic interference and poisoning. Her microphone and sensor arrays only receive perceptually valid data, ensuring robust real-world reliability in both quiet and noisy environments.
cycloneSensor Integrity Assurance
To prevent manipulation of movement or orientation data through sound, vibration, or signal injection, Synthia employs a multi-modal sensor architecture with diverse physical characteristics. Each of her inertial subsystems has proprietary redundancy features, and all motion data is cross-referenced against her visual system and context-aware behavioral models.
Certain subsystems are physically immune to high-frequency spoofing attempts, and the internal data pipeline includes proprietary pattern verification algorithms that reject unrealistic motion profiles. This ensures that balance, posture, and spatial awareness remain trustworthy—even in the presence of environmental noise or targeted disruption attempts.
visibilityVision System Resilience
Synthia’s camera array operates with multi-perspective sensing and non-deterministic sampling, including asynchronous frame capture and dynamic exposure control, mimicking the way biological systems perceive the world. This breaks the conditions required for most adversarial image attacks, including sticker-based misclassification, optical spoofing, or pattern-based illusions.
Vision-based decisions are always cross-validated using data from inertial sensors and behavioral context, creating a sensor fusion model that resists both passive and active visual manipulation. Her perception models are additionally trained to detect anomalies and refuse ambiguous visual cues, allowing her to default to safe, non-reactive behavior if unexpected data is received.
satellite_altFuture Features: Attack Source Detection & Reporting
As part of ongoing development, Synthia’s security platform is being extended with capabilities for localized attack source identification. In the near future, she will be able to:
- Detect and log attempted signal spoofing or jamming
- Determine the approximate direction and location of IR, visible light, or acoustic interference
- Notify the owner in real time of unusual activity, including potential hostile actions in her environment
The final response to detected tampering or attack attempts is left to owner discretion—Synthia will only provide the facts. Whether the response involves a polite conversation… or a more creative deterrent… is entirely up to you. 😇
