Photos of tickets for events such as concerts, games, theater, among others should not be published on social networks. These tickets, in general, have a bar code that is read at the entrance of the place and that can be replicated by third parties through the shared image. In addition to having the ticket duplicated, the person is at risk of not being able to enter the event if the impostor's ticket is scanned first by the system.

According to the security company Kaspersky, if a person really wants to share a ticket on Facebook or Instagram, for example, they must blur the barcode, as well as the numbers below it using an image editing app.

2. Photos of credit or debit cards

It seems obvious, but it does not cost to reinforce: images of credit cards, debit cards or any other bank information should not be published on the Internet. If the image is seen by a malicious person, the data can be used to make online purchases, which do not require the use of a password. So, before you post a picture of your card or an image of your bank balance, remember the risks.

3. Boarding passes or travel plans

When searching for the hashtag #boadingpass on Instagram, immediately, more than 107 thousand publications appear with photos of boarding passes that should not be being exposed on social networks. Like tickets, these tickets have bar codes. But that's not all: the document also presents information that goes beyond flight data, which can give access to the user's account on the airline's website.

With only the surname and the number of the record finder, it is possible to obtain information such as the phone number of someone and the future flights they have booked. In addition, it allows someone to enter and change their seats, as well as cancel any future flight, explains the How to Geek website.

Another tip for those who have a public account on the networks is to avoid disclosing travel plans, with information on how long to stay out, when to travel and the like. Criminals are increasingly specialized in looking at profiles and the information that a house is empty for a long season can be a big deal for bandits.

Your desk may contain more information than you think. Therefore, before sharing a photo in which it appears, check that there are no apparent important documents, adhesive notes, login and password displayed on the computer screen, invoices or notes with confidential data that may expose you or the company.

5. Home address and phone

This item may also seem obvious, but, yes, there are those who publicly share personal information such as address or telephone. For example, if someone creates an event on Facebook that will be hosted in their own home and keeps it public, it allows anyone to have access to their place of residence. It is also common for people, eager to receive contact from a company or celebrity, to leave their cell phone number in the comments of a Facebook post.

In addition, posting a photo of the front of your home, in which the number is visible, can be a way to facilitate access by criminals to the place. Especially in the case of smaller cities, where it is easier to recognize the place through details of the surroundings. Just in case, avoid.

Several platforms offer check in, which allow users to mark their current location and display it to all their contacts. Another way you can do this is that many people don't notice it through geotags in Instagram photos. The resource can be useful to show how fun an event is and attract more friends or to link your publications to a location, but it can also be dangerous.

Primarily because criminals who follow the posts have an indication that that user is not at home. Second, people with many possessions are more closely watched by these thugs and the precise information of where they are may be what was missing for a robbery or even kidnapping.

7. Photo of children with location and school uniform

A child's photo is always cute and, of course, parents like to show their friends special moments. However, it is important to be careful with the content, even if your profile on a social network is private, and not public. The Life Wire website suggests that guardians never post photos with geolocation and avoid informing their children's names on the Internet.

In addition, it is essential to avoid photos in which children appear in school uniforms. After all, the T-shirt indicates where they are studying and facilitates the action of possible criminals.
