The power of image…

…through the years!

History of image

• 30.000 years ago, our ancestors painted pictures on the walls of the caves they lived in.

• 5.000-2.000 years ago, ancient Greeks and Egyptians decorate their pots and paint the walls of houses and tombs.

• For centuries, artists from all over the world paint and create wonderful paintings, a important cultural heritage to humanity.

• On 1816 the first photograph was taken by Niepce.

The power of imageImage becomes a part of everyday life: • It pleases us. • It is a part of someone’s religion. • It helps us find our way. • It protects us.• It becomes a part of history.

All our life is based on signs and sometimes it seams that it depends on an image.

…Vision: one emotional communication

Body Language:

It is a broad term for forms of communication using body movements or gestures instead of, or in addition to, sounds, verbal language, or other forms of communication

In our daily lives we encounter many forms of body language gestures. These are a few examples:

And what about the signs we use to make with our hands and fingers? The meaning is not the same in different cultures!

Do we believe that pictures have the power to change:

• The attitude• Emotional state• Ideals• Our life• To provoke laugh or a light smile• Secret meaning of the words• Do we believe in what we can see on the

picture• The power of the pictures, made with a

mobile phone, their ability to gin the moment

…and safety on the WEB!

Have you ever upload your photos to a Photo-Sharing Web Site? If you have, do you have any idea about how safe this Web Site is?

The past few years there has been an increase in the number and popularity of publicly hosted Web sites for sharing digital photos since almost everyone today owns a digital camera or a mobile phone with digital camera. But is it safe to share personal photos on the Internet? Personal photos may contain personal information about us, our family and friends, our interests or hobbies. So, safety means that the personal information, which can be identified and extracted from these photos, is:

• Private: the access to the information can be restricted to the use of a particular person or group of people and the owner of the information should control who has access to it and

• Secure: free from danger and risk of loss, i.e., making sure that the bad people cannot access our information.

Photo-sharing Web sitesA photo-sharing Web site lets members upload and annotate photos that are posted on its site. Some sites offer these services for free, while others charge a fee, sometimes only for additional storage. In general, these sites make money by charging for prints, cards, and gifts such as calendars or coffee mugs imprinted with the photos. Members can share their photos by sending friends and family the URL of their photo site. Sometimes, visitors must enter a username and password in order to view the pictures and are able to leave comments about the photos they view. Some of the better-known photo-sharing Web sites are:

– Webshots (http://www.webshots.com)– Yahoo! Photos (http://photos.yahoo.com)– Shutterfly (http://www.shutterfly.com)– smugmug (http://www.smugmug.com)– Club Photo (http://www.clubphoto.com)– dotPhoto (http://www.dotphoto.com)– Fotopages (http://www.fotopages.com)– Snapfish (http://www.snapfish.com)

Access to our photosWhen you start using a service like this, we have to agree about some terms of use. For example, we agree to not use the service to upload, post, email, transmit or otherwise make available any content that is unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, libellous, invasive of another's privacy, hateful, or racially, ethnically or otherwise objectionable. It is reasonable to assume that some employees have to check content to make sure it complies with the terms of service. But who is protecting us from these employees?

• We don’t know who they are, or how many employees may have access to our pictures.

• And even worst, these employees may also be able to access, with or without their employer’s consent, other personal information, such as our name and address.

• And if we purchased something, such as additional storage space or prints of photos, employees may also be able to access our billing information, such as credit card number.

“sniffing” dataDo people know that someone may “sniff” data as it travel between their computer and the computer at the photo-sharing Web site? There are two ways this may happen:

• Someone may “sniff” our Internet traffic: someone may target us and watch information sent to and from our computer, such as photos or usernames and passwords, while we upload them to the Web site or view them. It is relatively easy to “sniff” a neighbour’s Internet traffic, particularly if we share the same broadband ISP. ISPs have similar terms-of-service agreements. While these agreements generally prohibit watching other customers’ traffic, it is easy to do so without being detected.

• Someone may “sniff” the Web site’s Internet traffic: someone may watch traffic to the Web site, such as the usernames and passwords when they entered the site, or the photos, while they were uploaded or viewed.

Passwords• While usernames and passwords may seem

secure, they are often transmitted to these sites without secure SSL encryption: they are generally encoded with basic authentication, which is not secure and is easy to decode. But can someone guess our password? This is easy to happen if we use a password that is easy to identify, such as one including a birthday, name, or another easy-to-guess choice. Or even the worst case: some people are not sufficiently computer-savvy to realize they should never reveal a password, even to an employee of a legitimate business. Anyone can trick them to reveal their password, pretending to be a Web-site engineer!

Online photo-albums• In some photo-sharing Web sites, we can visit other

people’s online photo albums. This means that if we post our pictures on this site, any visitor to the site can see them. If we want, we may disable this option, but only after we have create the online photo album. So for some time, at least, all posted photos are public, and we must do something specific to mark our photos as private. In other cases if we send a photo-sharing invitation, any recipient of that invitation could view that album even if it is set to private and anyone who can access the e-mail invitation can, by extension, access our personal photos on a Web site. Visitors can also search other people’s pages by country, or even input any term, such as a name or a location into the site’s search facility. This makes it easier to find specific information about a person or a place.

Personal informationWhen we post personal information on the Internet, we do so with a specific purpose in mind, such as sharing personal photos with our friends and family, or promoting our business. But once personal information is freely available on the Internet, we lose control and knowledge of how it ultimately will be used.

• Although usernames and passwords give us feeling of control, this is illusory, since that information is not sent securely, and in any case Web site employees can access our personal information.

• Or sometimes, personal photos become publicly accessible because of a problem with the software at the Web site.

• Any publicly accessible Web site is an unsafe place for personal or private information. Personal photos can powerfully convey a lot of information to those close to us, but when that information is not safeguarded, it may convey this same information to those who would harm us. Identifying details in pictures can be very dangerous.

• In addition, some photo-sharing sites let us annotate our pictures, and some sites let visitors leave publicly viewable comments. This is very dangerous, because even if we are careful about annotating pictures in a non-identifying way (without names and locations, for example), visitors to our site who share this knowledge may not be as careful.

ProtectionConclusion: since other people can access our photos on photo-sharing sites, without our consent or knowledge, these sites are neither private nor secure. Therefore, they are not a safe place to store personal information. How to protect ourselves:

• By avoiding putting any personal information on the Internet.• By making CDs containing personal photos and videos and distribute

those to friends and family in person or by mail.• By insisting that any photo sharing site where we post pictures uses

secure SSL encryption for transmitting usernames and passwords and data.

Plus:• By posting personal photos only on a Web site hosted on our computer.

This way, we control the information, and the access to it. This also prevents Web site employees from accessing our personal information.

• By insisting on secure passwords and treat them securely: use usernames and passwords to control who can access our personal information and not distribute them by e-mail, which is not secure, but by phone.

• By using SSL when transmitting sensitive information such as usernames and passwords as well as the personal information on our site.

The power of image…

…is the power of living together, of comprehend each other, of being supportive, of being friends!

Thank you very much!
