Early Disease Detection with Machine Learning and Deep Learning
In today’s healthcare landscape, early detection of diseases is a game-changer. Identifying health conditions early not only improves patient outcomes but also reduces treatment costs. Machine learning (ML) and deep learning (DL) are revolutionizing this process, enabling healthcare systems to detect diseases with unprecedented accuracy and speed.
Early detection of diseases like cancer, diabetes, and cardiovascular conditions can significantly improve survival rates. However, traditional diagnostic methods often rely on time-consuming tests and subjective interpretation, leading to delays or errors. Enter machine learning and deep learning: technologies that learn from vast datasets to identify patterns invisible to the human eye.
Cancer Detection: DL algorithms have achieved radiologist-level accuracy in detecting breast cancer from mammograms.
COVID-19 Diagnosis: AI models analyze chest CT scans to identify COVID-19 with high precision.
Alzheimer’s Detection: ML models analyze brain scans and cognitive tests to predict early-stage Alzheimer’s.
Despite its promise, deploying ML and DL in healthcare is not without challenges:
- Data Privacy: Ensuring patient confidentiality in large datasets.
- Bias and Accuracy: Models must be trained on diverse datasets to avoid biased results.
- Integration: Seamless integration with existing healthcare systems is essential.
The future is bright, with ongoing research focusing on improving model interpretability, robustness, and real-time applicability.
. INTRODUCTION TO CYBER CRIME
ReplyDelete“Cyber security is the protection of internet-connected systems, including hardware, software and data,
from cyber attacks”.
• “Cybersecurity” means protecting information, equipment, devices, computer, computer resource,
communication device and information stored therein from unauthorized access, use, disclosure,
disruption, modification or destruction.
• Almost everyone is aware of the rapid growth of the Internet.
• Given the unrestricted number of free websites, the Internet has undeniably opened a new way of
exploitation known as cybercrime.
• These activities involve the use of computers, the Internet, cyberspace and the worldwide web (WWW).
• Interestingly, cybercrime is not a new phenomena; the first recorded cybercrime took place in the year
1820.
• It is one of the most talked about topics in the recent years.
• Based on a 2008 survey in Australia, the below shows the cybercrime trend.
Cybercrime specifically can be defined in a number of ways; a few definitions are:
1. A crime committed using a computer and the Internet to steal a person’s identity (identity theft) or sell
contraband or stalk victims or disrupt operations with malevolent programs.
2. Crimes completed either on or with a computer.
3. Any illegal activity done through the Internet or on the computer.
4. All criminal activities done using the medium of computers, the Internet, cyberspace and the WWW.
Phishing, wire transfer, etc. and use it to their own advantage without the consent of the individual.
Phishing:
Phishing is a cyber attack that uses disguised email as a weapon. The goal is to trick the email recipient into believing that the message is something they want or need a request from their bank, for instance, or a note from someone in their company and to click a link or download an attachment.
Phishing is an attempt by an individual or a group to thieve personal confidential information such as passwords, credit card information from unsuspecting victims for identity theft, financial gain & other fraudulent activities.
Cyberpunk:
This is a term coined by Bruce Bethke, published in science fiction stories magazine in November 1983.
CYBERCRIME AND INFORMATION SECURITY
Lack of information security gives rise to cybercrimes. Let us refer to the amended Indian Information
Technology Act (ITA) 2000 in the context of cybercrime. From an Indian perspective, the new version of the Act (referred to as ITA 2008) provides a new focus on “Information Security in India". "Cybersecurity” means protecting information, equipment, devices, computer, computer resource, communication device and information stored therein from unauthorized access, use, disclosure, disruption, modification or destruction.
WHO ARE CYBERCRIMINALS?
Cybercrime involves such activities
• credit card fraud;
• cyberstalking;
• defaming another online;
• gaining unauthorized access to computer systems;
• ignoring copyright, software licensing and trademark protection;
• overriding encryption to make illegal copies;
• software piracy and stealing another’s identity (known as identity theft) to perform criminal acts
Types of Cybercriminals:
1. Type I: Cybercriminals – hungry for recognition
• Hobby hackers;
• IT professionals (social engineering is one of the biggest threat);
• Politically motivated hackers;
• Terrorist organizations.
2. Type II: Cybercriminals – not interested in recognition
• Psychological perverts;
• financially motivated hackers (corporate espionage);
• state-sponsored hacking (national espionage, sabotage)
Psychological perverts;
• financially motivated hackers (corporate espionage);
• state-sponsored hacking (national espionage, sabotage)
• organized criminals
Type III: Cybercriminals – the insiders
• Disgruntled or former employees seeking revenge;
• Competing companies using employees to gain economic advantage through damage and/or
theft
