Encryption security features that protect users of digital applications is becoming a hot topic. WhatsApp has announced the latest encryption end to end on their services that protect the privacy of user data. Ensuring end to end encryption of user data can not be arbitrarily intercepted by unauthorized parties.

Before WhatsApp, messaging services are already popular with encryption is the BlackBerry Messenger (BBM). Even the BBM encryption known as the safest in the world.

Observers digital forensics Indonesia, Alam said Ruby encryption systems work WhatsApp and BBM is theoretically more or less the same. Both apply encryption end to end.

"A problem is, (whether) each party withholding or not publish," said the expert to VIVA.co.id was born in Jakarta, on Thursday evening, April 7, 2016.

Ruby explains, for security work on the fuel system, known BlackBerry legally storing user data to six months back. Well, when required by law enforcement, the BlackBerry experience so far always been able to work together.

According to Ruby, in terms of cooperation with law enforcement, BlackBerry is cooperative in revealing conversations of data users. To that end, Ruby argued, WhatsApp also can imitate BlackBerry.

"First, he (WhatsApp) end-to-end encryption, for users in general. But if law enforcement is requested, WhatsApp can still provide data to law enforcement, according to the procedure of origin, to be legal, as it was," he said.

According to BlackBerry center ever dialogue with, a company from Waterloo, Ontario, Canada that reveal they will provide user data to law enforcement anywhere in the world in need. Of note, the data request in accordance with the procedures and rules applicable.

Ruby said in his confession, Canadian law enforcement have become accustomed to the data on fuel. The process of opening the data that it takes several days.

"They are accustomed to opening the data. Even just need three to four days, because they were quite ordinary, every day asking for the data," he said.

Meanwhile, regarding access to encryption, WhatsApp has given a sign that no one can tap or open a data user communication history.

Founder of WhatsApp, Jan Koum and Brian Acton in an announcement on the company's blog wrote, the service carries encrypted on WhatsApp simple idea. That user sends a message, and only certain people can read a personal message or group conversations that have been submitted. Even WhatsApp also asserted could not read its message.

"No one can see the message, not the cyber criminals and not the hacker. Also not oppressive regime, even us as well," they wrote.

Imaging Technology Reveals Secret Painting Rembrant

By: Syaifuddin Iqbal on 00:06

Advances in technology have prompted scientists to be able to dedicate himself in digging things are still unspoiled. Technology has now reach into every field, even to describe how a painting from the masterpiece created a masterpiece. The latest imaging technology has been used to see layer upon layer of paint and pencil used a famous artist, Rembrandt.

Art historians and scientists used imaging methods to explore and scan the virtual layer upon layer of a masterpiece painting. It is hoped that the information obtained can be a comparison of how an artist works or what kind of painting techniques used to produce a beautiful painting. This method is used to protect the original painting technique used because it is not nature does not destroy or injure the original work.

The study, led by Matthias Alfeld from the University of Antwerp in Belgium, which is published in Springer journals Applied Physics A: Materials Science and Processing, take the subject of the painting Susanna and The Elder works of Rembrandt van Rijn to be investigated and unearthed information. They use a combination of three imaging techniques to obtain valuable information as complete as possible about what is on the back of the complexity of the creation of a masterpiece in detail.

Rembrant van Rijn painting titled Susanna and The Elder, dated 1647 and tertandatangani it depends on Gemaldegalerie museum. An art museum in Germany where the painting has changes quite a lot of art called pentimenti under the existing composition. Pentimenti taken from the verb speaking Italian, which means pentire repent). Revealed in the 1930s by using X-ray radiography (XRR) first.

The investigation resumed in 1994 using neutron activation autoradiography (Naar-Neutron Activation autoradiography). In this technique the scientists discovered more hidden details about the changes made with pigments other than white lead (basic material oil paint on the painting). Then the team used a technique Fluorescence Alfeld macro-x-ray (MA-XRF) scan, the technique used can be done in one day by using this type of scanner home in a museum in Berlin. The results are then compared with the radiographic images of paintings. With imaging technology is expected to uncover the secrets contained within the painting, both the elements and painting techniques used.

Susanna and The Elder is a masterpiece of a great artist Rembrandt van Rijn that holds many secrets and spoil the eyes of lovers of painting because the optical effects of color created by the human mind can hypnotize

Alfeld team found that the images of the elements used are acquired by X-ray fluorescence scan the easiest to interpret. This is because most of the individual elements clearly separated. A broader elements can also be studied, compared to using autoradiography. However, X-ray fluorescence scan can be used to detect bone black on the surface of the painting and not the sub-surface layer, such as the hidden sketch found therein.

These three techniques (radiography X-ray early, Naar-Neutron Activation autoradiography and macro-X-ray fluorescence (MA-XRF) scan that has recently developed) revealed major changes made to the painting. Autoradiography is a very suitable tool for studying pigments such as bone black, umber, green and blue copper-based, smalt and vermilion, but not for calcium, iron and tin. It is also the only method that is able to visualize the phosphorus, an element which is nonetheless present in the sketch paintings, which are in color bone black, in the lower layers of paint. With the X-ray radiography and autoradiography, a single brush strokes can be seen, which helped study looking at the painting techniques used.

Alfeld team chose to investigate Susanna and The Elder not only because pentimenti obvious, but also because of its smaller size that makes it easier to scan. Given the relatively short time and little effort required for investigation using X-ray fluorescence scan, the technique is expected to be applied more often in the future by using autoradiography imaging technology. The ability of the latter method is able to visualize the distribution of certain elements through the strong absorption of the base layer, and the two other methods have provided supplementary information.

Death and Aging Can Be Delayed

By: Syaifuddin Iqbal on 23:47

Frightening possible for us layman, but is a new thing at once breakthrough for scientists mreka. A death pastiakan toward all living beings on this earth, including humans. No one knows when death will datang.Tapi, a recent research conducted by researchers at the Institute of Health Aging at University College London, UK, gave birth to the new theory, the researchers discovered that the dying process occurs slowly. And, even more surprising, the death process can be delayed like we postpone the schedule of activities.

Worms as test objects while as quoted from several sources on the internet, the researchers see indications of the coming death of the worm that spreads through blue light on the cells in the body. The blue-colored liquid known as fluorescent, or a substance that has absorbed light or other electromagnetic radiation. Fluorescence is widely used in the fields of mineralogy, gemology, chemical sensors (fluorescence spectroscopy), fluorescent labeling, coloring, and biological detectors. The researchers observed the process of death worm did not occur in all parts of the body simultaneously, but slowly.

As a result of a disease, the cells in the worms die one by one. "We identified a chemical pathway that causes the destruction of the worm body cells die, that we can see from the fluorescent light that lights up in the body of the worm," said David Gems of the Institute of Health Aging at University College London, as reported by various media.

"The wave of death from intestinal worm starts then spread throughout the body. The more blue light that spreads throughout the body of the worm, the worm it will be closer to death, "Dr. Cassandra Coburn add, as the principal investigator of the research reported by The Huffington Post, July 26, 2013.

"When the fluorescent light was fading, then it indicates the worm was dead. But, we see the waning light occurs gradually, "explains Gems.Temuan raises new theory that the extinction of the fluorescent light can be blocked prior to postpone death, to rescue the cells that are still in good shape." This proves that the old age actually does not affect cells in the body. However, cell death is a parallel activity, ". "We're thinking of a way to disrupt the chemical processes that lead to death, so that death can be postponed," added Gems.Saat this, the team is focusing on studying the biological events that occur in the aging process of living beings.

Life prediction

Talk about aging, similar to the above study, another study researchers conducted a set of King's College, England, discovered new techniques in a blood test, which can predict how soon a person will grow old. Results of this study seemed to pave the way for the development of treatment of diseases associated with aging person.

Reported by the Telegraph, the research team has identified a chemical marker known as metabolites in human blood, which is closely linked to aging. The results showed one of 22 metabolites were found in human blood can indicate the condition of human aging.

Researchers also believe the new breakthrough in human blood testing can megindetifikasi problem of aging, or even death. According to Ana Valdes, principal researcher at King's College, 22 metabolites associated with aging detectable in the blood. "So, in the future we can predict a person's age and the aging of the blood samples". He explained that the metabolite is also specifically associated with lung function, bone mineral density, and weight at the time of the human birth. "It could be used to determine a person's age," said Valdes. as reported by the source.
