Intelligent transportation systems (ITS) use advanced technologies such as artificial intelligence to significantly improve traffic flow management efficiency, and promote the intelligent development of the transportation industry. However, if the data in ITS is attacked, such as tampering or forgery, it will endanger public safety and cause social losses. Therefore, this paper proposes a watermarking that can verify the integrity of copyright in response to the needs of ITS, termed ITSmark. ITSmark focuses on functions such as extracting watermarks, verifying permission, and tracing tampered locations. The scheme uses the copyright information to build the multi-bit space and divides this space into multiple segments. These segments will be assigned to tokens. Thus, the next token is determined by its segment which contains the copyright. In this way, the obtained data contains the custom watermark. To ensure the authorization, key parameters are encrypted during copyright embedding to obtain cipher data. Only by possessing the correct cipher data and private key, can the user entirely extract the watermark. Experiments show that ITSmark surpasses baseline performances in data quality, extraction accuracy, and unforgeability. It also shows unique capabilities of permission verification and tampered location tracing, which ensures the security of extraction and the reliability of copyright verification. Furthermore, ITSmark can also customize the watermark embedding position and proportion according to user needs, making embedding more flexible.

High-tech tools, including an undersea "mountain goat," and years of research led to the discovery of the WWII-era Musashi in the Pacific.

High-tech tools, including an undersea "mountain goat," and years of research led to the discovery of the WWII-era Musashi in the Pacific. WATCH: Footage from an unmanned submersible shows wreckage of the World War II battleship. After years of meticulous historical research and seafloor terrain analysis, it was an underwater "mountain goat" that ultimately found the wreck of one of history's most impressive battleships, the Musashi.

The stern of a US destroyer that was blown off the ship by a Japanese mine 75 years ago, killing 71, has been found off Alaska. The fragment of the USS Abner Read was found in the Bering Sea off the Aleutian island of Kiska, where it sank after being torn off by an explosion while conducting an anti-submarine patrol. The remaining crew managed to save the ship, which was repaired after the attack. On July 17, a NOAA-funded team of scientists from Scripps Institution of Oceanography at the University of California San Diego and the University of Delaware discovered the missing 75- foot stern section in 290 feet of water off of Kiska, one of only two United States territories to be occupied by foreign forces in the last 200 years. After sonar mounted to the side of the research ship Norseman II identified a promising target, the team sent down a deep-diving, remotely operated vehicle to capture live video for confirmation.

More than 60 years after it was blown up by two atomic blasts then later sunk off the cost of California, the wreckage of the historic USS Independence has been seen for the first time. After being found in April this year, the Ocean Exploration Trust (OET) has now explored the wreck with robotic submarines, and released the first close-up images of how the ship looks now. This exploration is revealing the ship holds war secrets, including a fighter plane within the sunken aircraft carrier. After being found in April this year, a team of divers from the National Oceanic and Atmospheric Administration ( NOAA) has now explored the wreck with robotic submarines, and released the first close-up images of how the ship looks now.

Scientists have released incredible pictures of sunken light aircraft carrier USS Independence that were taken by underwater robots exploring the wreck. The historic ship, which served in World War II and was used in the atomic tests at Bikini Atoll in the Pacific, was intentionally sunk off California in 1951. The 622-foot-long Independence sits in 2,600 feet of water in the Greater Farallones National Maritime Sanctuary. Experts on the research vessel E/V Nautilus are using two Remotely Operated Vehicles (ROVs) to study the ship, which has been described as "amazingly intact" by National Oceanic and Atmospheric Administration (NOAA) scientists. The robots' initial dive began on Monday and they have already sent back a number of eerie images from the wreck.

Stunning new pictures from a 1946 atomic weapon test on a hundred US ships have been revealed. The newly declassified images show the World War II veteran aircraft carrier USS Independence, which was one of nearly a hundred ships used as targets in the first tests of the atomic bomb at Bikini Atoll in the summer of 1946. The two Bikini tests known as Operation Crossroads were carried out in the immediate aftermath of the atomic end to World War II in Japan, and signaled a new era in world history, the historians involved in the new study say.
