Let's take a closer look –
What is Multimedia Forensics?
A subfield of digital forensic science known as multimedia forensics examines multimedia contents (text, photos, music, video, and 3D models) with the goal of recovering, authenticating, examining, and analyzing such digital devices-often in relation to social media, computer crimes, and mobile devices. It seeks to:
- Disclose the origins of digital content.
- Verifying the accuracy of the information.
- Determining which acquisition equipment generated the data.
- Information retrieval from multimodal signals.
What is Cybersecurity?
The process of preventing unwanted access, disclosure, usage, alteration, interruption, or destruction of networks, computer systems, and data is known as Cybersecurity. It includes a variety of tools, tactics, and regulations designed to protect digital assets from online dangers like as phishing, malware, and hacking. In essence, Cybersecurity guarantees the availability, confidentiality, and integrity of data and systems.
