Abstract
A method for processing signals of active sensor systems including processing an emitted signal to include at least one distinguishing feature, the emitted signal emitted by an active sensor system adapted to intercept a reflection of the emitted signal, and to analyze the reflection of the emitted signal for determining at least one parameter of at least one object located in a space, analyzing an intercepted portion to verify the at least one distinguishing feature in the intercepted portion, and processing the intercepted portion as the reflection of the emitted signal when the at least one distinguishing feature is verified.
Claims18
A method for processing signals of active sensor systems, comprising:
- processing a signal to include at least one distinguishing feature, wherein the signal is emitted by an active sensor system adapted to intercept at least a reflection of the emitted signal or a portion of the emitted signal and to analyze the reflection of the emitted signal for determining at least one parameter of at least one object located in a space;
- analyzing the intercepted portion to identify when the at least one distinguishing feature is present in the intercepted portion;
- classifying the intercepted portion as an unverified signal when the distinguishing feature is identified as not present in the intercepted portion;
- and
- as a response to identification of the presence of the at least one distinguishing feature, processing the intercepted portion as a verified signal;
- wherein the emitted signal is emitted by headlights of a vehicle;
- and
- wherein said active sensor system comprises at least one sensor for intercepting said reflection.
A monitoring device for processing signals of active sensor systems to prevent emulating or tempering reflections of the signals by a malicious entity, comprising:
- an encoder or a modulator adapted to process a signal emitted by an active sensor system to include at least one distinguishing feature, wherein the active sensor system comprises a receiver for intercepting at least a portion of the emitted signal or of a reflection of the emitted signal so as to allow analyzing the reflection for determining at least one parameter of at least one object located in a space;
- a decoder or a demodulator adapted to decode or demodulate at least the intercepted portion;
- and
- at least one processor adapted to verify the at least one distinguishing feature in the decoded or demodulated signal and to instruct processing the reflection of the emitted signal as a verified signal only when the at least one distinguishing feature is verified;
- wherein the emitted signal is emitted by headlights of a vehicle;
- and
- wherein said active sensor system comprises at least one sensor for intercepting said reflection.
