Provided are systems and methods for increasing vehicle safety by determining whether a driver can operate a vehicle based on whether the physical status of the driver and the identity of the driver are acceptable. A first set of sensors may determine the physical status of the driver. The first set of sensors may include an electrocardiogram detection component, an alcohol detection component, a body temperature detection component, and a photography component, among others. A second set of sensors may determine the identity of the driver. The second set of sensors may a fingerprint detection component, an electrocardiogram detection component, and a photography component, among others. When it is determined that the physical status of the driver is unacceptable, the method may include activating an automatic driving system.

The method of claim 1, further comprising determining the physical status of the driver is unacceptable when the electrocardiogram detection component detects that the cardiac activity of the driver indicates that the likelihood of cardiac arrest of the driver exceeds a certain threshold. 3. The method of claim 2, wherein an electrocardiogram signal is extracted from the cardiac activity of the driver, and wherein the P wave, Q wave, R wave, S wave, and T wave are extracted from the electrocardiogram signal. 4. The method of claim 1, further comprising determining the physical status of the driver is unacceptable when the alcohol detection component detects that the breathing gas of the driver indicates that the blood alcohol content of the driver exceeds a certain threshold. 5. The method of claim 1, further comprising determining the physical status of the driver is determined to be unacceptable when the body temperature detection component detects that the body temperature of the driver is above or below certain thresholds. 6. The method of claim 1, further comprising determining the physical status of the driver is unacceptable when the photography component detects that the eye expression of the driver indicates that the likelihood of drowsiness exceeds a certain threshold. 7. The method of claim 1, wherein the identity of the driver is determined to be acceptable when the fingerprint detection component detects that the fingerprint of the driver matches a fingerprint stored in a server of acceptable driver fingerprints. 8. The method of claim 1, wherein the identity of the driver is determined to be acceptable when the electrocardiogram detection component detects that the cardiac activity of the driver matches a cardiac activity stored in a server of acceptable driver cardiac activities. 9. The method of claim 1, further comprising: activating, at the processor within the vehicle, an alarm system when it is determined that the identity of the driver is unacceptable. 10. The method of claim 1, further comprising: activating, at the processor within the vehicle, an automatic driving system when it is determined that the physical status of the driver is unacceptable. 11. A system configured to determine whether a driver is permitted to start a vehicle, the system comprising a processor configured to perform: determining, at a processor within the vehicle, whether a physical status of the driver is acceptable using a first set of sensors, wherein the determining whether the physical status of the driver is acceptable comprises: determining whether a cardiac arrest risk of the driver is within a certain cardiac threshold by automatically sampling a cardiac activity of the driver with an in-vehicle electrocardiogram detection component;in response to determining the cardiac arrest risk of the driver is within a certain cardiac threshold, determining whether an alcohol level in a breathing gas of the driver is below a certain alcohol threshold by automatically sampling the breathing gas of the driver using an alcohol detection component;in response to determining the alcohol level of the driver is below the certain alcohol threshold, determining whether a body temperature of the driver is within a range of predetermined normal body temperatures by automatically sampling the body temperature of the driver using a body temperature detection component;in response to determining the body temperature of the driver is within the range of the predetermined normal body temperature, determining whether an eye expression of the driver indicates a risk of the driver is below a certain drowsiness threshold by sampling the eye expression of the driver using a photography component; andin response to determining the risk of the driver exceeds the certain drowsiness threshold, determining the physical status of the driver is not acceptable;determining, at the processor within the vehicle, whether the identity of the driver is acceptable using a second set of sensors, wherein the identity of the driver is acceptable when the second set of sensors indicate that the driver is an authorized driver, and wherein the second set of sensors include at least one of the following: a fingerprint detection component configured to detect a fingerprint of the driver;the electrocardiogram detection component configured to detect the cardiac activity of the driver; andthe photography component configured to detect an image of the driver; andin response to determination that the identity of the driver is acceptable and the determination that the physical status of the driver is not acceptable, activating, at the processor within the vehicle, an automatic driving system. 12.
