World biometric industry income reached $1.5 billion in 2005
A trick reminiscent of a fun-house mirror might improve the security and privacy of the access-control technology that examines fingerprints, facial features or other personal characteristics.
In such systems, known as biometrics, a computer generally reduces an image to a template of “minutia points”, notable features such as a loop in a fingerprint or the position of an eye.
Those points are converted to a numeric string by a mathematical algorithm, then stored for later analysis.
But those mathematical templates, if stolen, can be dangerous.
So researchers have developed ways to alter images in a defined, repeatable way, so that hackers who managed to crack a biometric database would be able to steal only the distortion, not the true, original face or fingerprint.
Charles Palmer, head security researcher for International Business Machines Corp., believes biometric fraud will become more sophisticated and problematic as border crossings, passports, financial networks, personal computers and even checkout counters increasingly use the technology.
Worldwide biometric industry revenue is expected to soar from $1.5 billion this year to $5.3 billion in 2010, with government and law enforcement accounting for almost half of the total, according to the International Biometric Group, a consulting firm.
Biometric fraud
“My Social Security number is not secret. My mother’s maiden name isn’t secret. What’s worse, passwords aren’t secret”
James Wayman,
Biometrics expert
While a standard biometric can’t be torn up and reissued like a credit card or password, since it’s based on unchanging aspects of a person’s physical appearance, distortion makes that possible.
A bank or an office building that had its biometrics compromised could register new ones simply by changing the way it transforms images.
That’s why IBM calls this “cancellable biometrics.”
The method has been discussed in research circles for several years, and at least one biometrics vendor, iris-scanner Iridian Technologies Inc., says it offers a cancellable system.
Iridian alters the computer-generated template rather than the original image, but the effect is the same.
“You can’t take a biometric out of one application and replay it in another,” said Frank Fitzsimmons, Iridian’s chief executive.
Perhaps the biggest benefit, experts contend, could be to improve public perceptions about what happens to biometric data behind the scenes as the technology becomes more widespread.
If an organisation can check only its version of distorted biometrics, that could reduce fears, some realistic, some paranoid, that government or big companies might maintain a vast database of biometric data for intrusive tracking or
marketing purposes.
Privacy
The system “could be understood as being more privacy-protected by the normal, everyday consumer,” said Philip Youn, a consultant with the International Biometric Group.
Even so, Youn said the distortion approach might not necessarily offer significantly better privacy than systems in which biometric data are not stored in vulnerable, centralized databases but rather on chip-embedded “smart” cards that people carry with them. In that scenario, the biometric reader determines simply that the person with the card is the person originally granted the card.
Other security experts said the cancellable method is a smart way to add a layer of protection to a technology that has some security holes despite being hailed as a huge improvement over more commonly used security measures.
“This is probably a nice thing to have, but it doesn’t resolve all the issues,” said James Wayman, a biometrics expert at San Jose State University.
After all, Wayman said, biometrics are not secret, they’re based on physical characteristics that we carry around in plain sight.
There’s no guarantee someone couldn’t lift your real-life fingerprint or take a picture of your face, then figure out a way to present those images to a biometric system.
“But I don’t want to pick on biometrics,” Wayman said.
“My Social Security number is not secret. My mother’s maiden name isn’t secret. What’s worse, passwords aren’t secret.”

Preparation:
Learn about the organization.
Have a specific job or jobs in mind.
Review your qualifications for the job.
Be ready to briefly describe your experience, showing how it relates it the job.
Be ready to answer broad questions, such as “Why should I hire you?” “Why do you want this job?” “What are your strengths and weaknesses?”
Practice an interview with a friend or relative. More....
Evaluating a Job Offer
Once you receive a job offer, you must decide if you want the job. Fortunately, most organizations will give you a few days to accept or reject an offer.
There are many issues to consider when assessing a job offer. Will the organization be a good place to work? Will the job be interesting? Are there opportunities for advancement? Is the salary fair? Does the employer offer good benefits? Now is the time to ask the potential employer about these issues—and to do some checking on your own.
The organization. Background information on an organization can help you to decide whether it is a good place for you to work. Factors to consider include the organization’s business or activity, financial condition, age, size, and location.
You generally can get background information on an organization, particularly a large organization, on its Internet site or by telephoning its public relations office. A public company’s annual report to the stockholders tells about its corporate philosophy, history, products or services, goals, and financial status. Most government agencies can furnish reports that describe their programs and missions. Press releases, company newsletters or magazines, and recruitment brochures also can be useful. Ask the organization for any other items that might interest a prospective employee. If possible, speak to current or former employees of the organization.
Background information on the organization may be available at your public or school library. If you cannot get an annual report, check the library for reference directories that may provide basic facts about the company, such as earnings, products and services, and number of employees. Some directories widely available in libraries either in print or as online databases include:
Dun & Bradstreet’s Million Dollar Directory
Standard and Poor’s Register of Corporations
Mergent’s Industrial Review (formerly Moody’s Industrial Manual)
Thomas Register of American Manufacturers
Ward’s Business Directory
Stories about an organization in magazines and newspapers can tell a great deal about its successes, failures, and plans for the future. You can identify articles on a company by looking under its name in periodical or computerized indexes in libraries, or by using one of the Internet’s search engines. However, it probably will not be useful to look back more than 2 or 3 years.
The library also may have government publications that present projections of growth for the industry in which the organization is classified. Long-term projections of employment and output for detailed industries, covering the entire U.S. economy, are developed by the Bureau of Labor Statistics and revised every 2 years. Trade magazines also may include articles on the trends for specific industries.
Career centers at colleges and universities often have information on employers that is not available in libraries. Ask a career center representative how to find out about a particular organization.
During your research consider the following questions:
Does the organization’s business or activity match your own interests and beliefs?
It is easier to apply yourself to the work if you are enthusiastic about what the organization does.
How will the size of the organization affect you?
Large firms generally offer a greater variety of training programs and career paths, more managerial levels for advancement, and better employee benefits than do small firms. Large employers also may have more advanced technologies. However, many jobs in large firms tend to be highly specialized.
Jobs in small firms may offer broader authority and responsibility, a closer working relationship with top management, and a chance to clearly see your contribution to the success of the organization.
Should you work for a relatively new organization or one that is well established?
New businesses have a high failure rate, but for many people, the excitement of helping to create a company and the potential for sharing in its success more than offset the risk of job loss. However, it may be just as exciting and rewarding to work for a young firm that already has a foothold on success.
The job. Even if everything else about the job is attractive, you will be unhappy if you dislike the day-to-day work. Determining in advance whether you will like the work may be difficult. However, the more you find out about the job before accepting or rejecting the offer, the more likely you are to make the right choice. Consider the following questions:
Where is the job located?
If the job is in another section of the country, you need to consider the cost of living, the availability of housing and transportation, and the quality of educational and recreational facilities in that section of the country. Even if the job location is in your area, you should consider the time and expense of commuting.
Does the work match your interests and make good use of your skills?
The duties and responsibilities of the job should be explained in enough detail to answer this question.
How important is the job to the company or organization?
An explanation of where you fit in the organization and how you are supposed to contribute to its overall goals should give you an idea of the job’s importance.
What will the hours be?
Most jobs involve regular hours—for example, 40 hours a week, during the day, Monday through Friday. Other jobs require night, weekend, or holiday work. In addition, some jobs routinely require overtime to meet deadlines or sales or production goals, or to better serve customers. Consider the effect that the work hours will have on your personal life.
How long do most people who enter this job stay with the company?
High turnover can mean dissatisfaction with the nature of the work or something else about the job.
Opportunities offered by employers. A good job offers you opportunities to learn new skills, increase your earnings, and rise to positions of greater authority, responsibility, and prestige. A lack of opportunities can dampen interest in the work and result in frustration and boredom.
The company should have a training plan for you. What valuable new skills does the company plan to teach you?
The employer should give you some idea of promotion possibilities within the organization. What is the next step on the career ladder? If you have to wait for a job to become vacant before you can be promoted, how long does this usually take? When opportunities for advancement do arise, will you compete with applicants from outside the company? Can you apply for jobs for which you qualify elsewhere within the organization, or is mobility within the firm limited?
Salaries and benefits. When an employer makes a job offer, information about earnings and benefits are usually included. You will want to research to determine if the offer is fair. If you choose to negotiate for higher pay and better benefits, objective research will help you strengthen your case.
You may have to go to several sources for information. One of the best places to start is the information from the Bureau of Labor Statistics.
You should also look for additional information, specifically tailored to your job offer and circumstances. Try to find family, friends, or acquaintances who recently were hired in similar jobs. Ask your teachers and the staff in placement offices about starting pay for graduates with your qualifications. Help-wanted ads in newspapers sometimes give salary ranges for similar positions. Check the library or your school’s career center for salary surveys such as those conducted by the National Association of Colleges and Employers or various professional associations.
If you are considering the salary and benefits for a job in another geographic area, make allowances for differences in the cost of living, which may be significantly higher in a large metropolitan area than in a smaller city, town, or rural area.
You also should learn the organization’s policy regarding overtime. Depending on the job, you may or may not be exempt from laws requiring the employer to compensate you for overtime. Find out how many hours you will be expected to work each week and whether you receive overtime pay or compensatory time off for working more than the specified number of hours in a week.
Also take into account that the starting salary is just that—the start. Your salary should be reviewed on a regular basis; many organizations do it every year. How much can you expect to earn after 1, 2, or 3 or more years? An employer cannot be specific about the amount of pay if it includes commissions and bonuses.
Benefits also can add a lot to your base pay, but they vary widely. Find out exactly what the benefit package includes and how much of the cost you must bear.
