Ranchi engg students say they have antidote to coded messages
Two Ranchi engineering students have designed a computer methodology which they say can stop steganographic or coded messages from being transferred through the internet.
Steganography is the fabled process of hiding information in plain sight in the internet within graphics and photos with jpeg, gif, and bmp files. The advantage of steganography is that the intended secret message does not attract attention to itself.
“It is possible that on social media most of us are regularly sharing pictures that have crucial messages for terror outfits,” said 23-year-old Pratik Kumar, who along with Rakesh Kumar, 24, developed the technology.
The two are engineering students at the Cambridge Institute of Technology in Ranchi and have worked for a year to develop the process. They said their methodology, RAKS. M. PK 1.0, had been approved by the International Journal of Computer Science and Communication (IJCSC) and British Journal of Mathematics and Computer Science, an open peer-reviewed journal.
“Unfortunately, none of the social networking sites use any technology to detect such images,” said Rakesh.
Cyrptography and steganography have been in use since ages. The difference between two is, in cryptography, cyber sleuths can tell a message has been encrypted, but can’t decode without knowing the key. In steganography, it might not be tough to decode the message in itself, but most people won’t detect the presence of the message. Pratik said their methodology could detect pictures that have encrypted information and prevent such pictures from being uploaded on social media.
The two have written to Facebook offering the computer methodology, but said were yet to get a reply.
Prakhar Prasad, an information security expert said Facebook and Twitter compress pictures while uploading. The process eliminates most of the encrypted messages as the compressed image is created from scratch using the uploaded image. However, he said steganography cannot be eliminated entirely. While the students claim their methodology can eliminate steganography with 100% efficiency, Prasad said “nothing can have 100% efficiency because there will always be edge cases in which the logic will fail to detect images with steganographic content.”
Nationalist Congress Party leaders Anil Deshmukh and Nawab Malik and Sena leader Sanjay Raut, who have been arrested in money laundering cases by the Enforcement Directorate, are now lodged in Arthur Road Jail in three different barracks. Malik, who was arrested in February in a money laundering case, is currently admitted to the Criti Care Hospital in Kurla for treatment. He is admitted to a private hospital for the last two months.
The Jammu and Kashmir government on Saturday terminated four employees from service, including the son of Hizbul Mujahideen chief Syed Salahuddin and wife of former militant Bitta Karate - amid probe over terror links, officials said on Saturday. Dr Muheet Ahmad Bhat, and Majid Hussain Qadiri - both of them linked to the University of Kashmir - are the two others employees who have been sacked.
Suspected militants targeted paramilitary CRPF with a grenade in Srinagar on Saturday, just a day ahead of Independence Day. A CRPF personnel was injured in the attack in the Old City, Eidgah. Srinagar police said that the CRPF personnel received minor injuries in the attack. Local reports said that the grenade was lobbed towards a CRPF bunker in Eidgah in which a sub-inspector of the CRPF was wounded.
Jammu and Kashmir Lt Governor Manoj Sinha on Saturday said that within a year government will push the last nail in the coffin of terrorism. Sinha today laid the foundation stone of 25 District Development Council and Block Development Council buildings in J&K, besides inaugurating 1000 Amrit Sarovars across J&K UT, in a function at SKICC, Srinagar.
IAS officer Shah Faesal who had resigned from his job and reinstated in April has been posted as deputy secretary in the Union Ministry of Tourism. He was detained at the Delhi airport on August 4, 2019, a day before Parliament pushed through constitutional changes, revoking Article 370 and 35A that granted special status to Jammu and Kashmir and bifurcating the erstwhile state into two Union Territories of J&K and Ladakh.
